DARK HERESYPLANETARY INFORMATION GENERATOR

The Imperium of the Dark Heresy game

contains millions of settled planets. Such is the

number of these planets that an almost limitlessvariety of environments can be created for the

setting of your game. Below is detailed a method

for generating planetary information, and a standard

layout for presenting the information.

The steps below allow the generation of a planet

within the Imperium that holds some form of

settlement and society. Obviously, there are many

more planets in the galaxy that are devoid of life

than there are which bear civilisation: in any stars

system, usually only one, sometimes two, rarely

three, and virtually never more than that of the

planets will be settled. Most of the planets in a

system are simply too inhospitable, even for the

most inventive of colonists or strongest and mostlengthy terra-forming projects. The steps detailed

below for generating a planet will create a planet

that is within the parameters where civilisation can

be easily established, or made possible by the

stubbornness of humanity and the technology of the

Adeptus Mechanicus. Many planets exist beyond

the variations possible on the following tables, but

these planets rarely, if ever, possess any significant

settlements.

Some of the steps have tables which allow you

to randomly generate traits for the planet, all of

which use a d100, and some of which will then

require the rolling of one or more d10 to get a

further definition. Other steps have no random

tables, and are merely a suggestion of what kind of

details you should create for the planet to make it

complete and distinctive.

When generating a planet you can use as many

of the random tables as you wish, or you can simply

select one of the options from each table. While it

can be entertaining to randomly generate as many

of the planets features as possible, a planet is

sometimes being created because it is required for a

particular scene or scenario in a game of Dark

Heresy, so the randomly generated traits may not be

suitable or desirable: the GM should ignore or re-

roll any features that do not suit the requirements or

tone of the game being played, or simply select the

most suitable.The details generated by this system provide

only the basics of a planets size, geography and

social basics. The details, colour and flavour must

be added by the GM and players as required by

their Dark Heresy campaign.

CLASS: The class of a world describes what

type of planet it is, what kind of civilisation and

society can be found on the planet, what level oftechnology is commonly used on the world, and

what kind of relationship the people of the planet

have with the Imperium.

worlds are worlds that previously had another class

before being subjected to whatever event gave them

their current class. Roll again to determine theplanets original class.

TECH LEVEL: The level of technology

common on a planet will determine a lot about its

society and economy, and will limit what is

available to be bought and traded there.

The tech level given for a world is not an

absolute limit on what can be found there; it is

simply a measure of what technological level the

indigenous people are at, and is what is most

common on the world. An Industrial world can

still have a spaceport in orbit and a High Imperial

settlement as its capital; the mass of the locals are

simply kept at the lower level so that they are easierto control and administer.

The tech level of a planet is determined by

generating a value based on the class of the world.

Stone Age worlds are inhabited by people who

live in small family groups, dwell in caves or rough

shelters and use only the most basic of tools made

of stone. People survive by hunting and gathering.

On Iron Age worlds the people have started to

learn how to shape and work iron to make more

effective tools and weapons. They are also living in

more substantial and sturdy buildings. Hunting and

gathering is still common, though small farms may

be seen dotted about.

Steel Age worlds have seen the use of iron

evolve into the manufacture of alloys to make steel

for weapons, armour and tools. Farming and trade

are ways of life for most people, and civilisation

has started to gather in fortified villages and towns.

The ruling classes live in large stone castles.

Communication networks of couriers and carrier

birds are common.

The poor people ofPre-Industrial worlds live

mostly by farming, and there is a richer class

starting to make use of new technologies and

mechanical devices to aid in manufacturing.Printing presses make education and distribution of

information more efficient.

Industrial worlds have completely moved on

from small farms and independent manufactories.

Everything in mechanised and automated. The

population mostly live in large cities, and

computers are starting to become common in all

things. Solid projectile weapons are the norm for

military forces, and advanced armour has started to

appear for personnel and vehicles.

Early Space worlds have developed basic space

flight, and may have established settlements on its

own moons, and even close neighbouring planets in

the same system. Basic las weapons may have been

developed.

Advanced Space worlds have explored their

own system, and colonised any viable planets to be

found there. Las weapons are common, and

cybernetics are starting to become practical.

Warp Space worlds have seen the development

of warp drives and Geller fields, and the inhabitants

are capable of travelling in the galaxy beyond their

own system. Powerful computers are common.

cybernetics and advanced medical techniques have

been developed that border on Imperial level

augmentation and rejuvenants. Primitive models of

more advanced weapons, like plasma and needle

weapons, are exceptional but present.

Low Imperial worlds are where the advanced

technologies of the Imperium start to be seen, but

are not always available. Standard issue and

common weapons and armour can be easily found,

but rare, expensive or very high tech items are still

unavailable most of the time (no items with rare or

very rare availability can be found on these worlds).

Most Imperial worlds are Mid Imperial tech

level, where most of the technology of the

Imperium can be found. Only the most obscure or

scarcely found items of technology cant be found

on these worlds (very rare availability items cannot

be purchased).

High Imperial worlds are the peak of Imperium

technological advancement outside of the greatesthive worlds and Adeptus Mechanicus worlds.

Anything and everything that can be bought on the

open market can be found on these worlds, and the

local troops have access to the most advanced

weapons, armour and equipment.

Advanced worlds are those that have access to

limited or developing technology. In the Imperium

of humankind only the greatest hive worlds and

forge worlds have this level of technology.

SIZE OF STAR: The size of the star that a

planet orbits can have a significant effect on the

economy and military importance of the planet, as

the gravity well projected by the star determines the

size of the systems warp zone.

GALACTIC POSITION: The coordinates

which describe the planets location in the galaxy.

The coordinates are given as 5 pieces of

information, and is written with each separated by a

slash, like this: AB/CDE/FG/123/456

The first two letters are used to indicate what

Segmentum the planet is in. The codes used are: SOfor Solar, OB for Obscurus, PA for Pacificus, TE

for Tempestus and UL for Ultima.

The next piece of information is a three letter

code that indicates the sector of space that the

planet is in. In the case of Calixis CAL is used.

Every sector of the Imperium has its own three digit

code that is used in the coordinates of planets in

that sector.

Third is a two letter code that indicates what

sub-sector of the indicated sector the planet is in.

Calixis sub-sectors use the following codes: PE for

The Periphery, MM for the Markayn Marches, MA

for Malfian, GR for Golgenna Reach, JR for Josian

Reach, DM for Drusus Marches, AD for Adrantisand HA for Hazeroth.

On the last page of this article there is a chart of

the Calixis Sector. This chart is divided into

squares, each 2 light years across. The squares are

numbered across the bottom (Trailing) edge and up

the left (Rimward) edge. These numbers are used as

grid reference coordinates to indicate a planets

location within the sector.

The first three-digit number is used to indicate

the planets grid reference along the Trailing edge.

The second three-digit number is used to indicate

the planets grid reference up the Rimward edge.

The first two digits in each case indicates what

square the planet is in, and the third digit is a

measure of how many tenths of a square the planet

lies into the square.

Using this system it is easy to give the location

of any planet in the Imperium.

(Obviously this system is not precise enough for

stellar navigation, but it adequately fills the role of

allowing us to plot a planets location for purposes

of game-play).

SECTOR: The galaxy of the Imperium is

divided into administrative sectors, each of which

has its own sector governor and administratum

infrastructure. While each sectors administration

and authority is obviously still beholden to the

powers of Holy Terra, they are mostly self

functioning and largely autonomous. A sector

usually also has a Conclave of the Inquisitionassigned to watch over it, led by a Lord Inquisitor.

SUB-SECTOR: All sectors are divided into

sub-sectors, and this is which sub-sector the planet

can be found in.

PLANETARY GOVERNOR: One person on

each planet is held responsible for the payment of

the required tithe when the Imperium shows up to

collect. The manner in which the planet is governed

and the methods used to gather the tithe are beyond

the concern of the Imperium. All the powers of

Terra care to know of planetary politics is who the

responsible individual is. The title used on the

planet varies from place to place; Governor is

simply a generic title used for bureaucratic ease.

ADEPTA PRESENCE: The branches of the

Adeptus Terra are present on different worlds in

varying degrees. To determine what Adepta are

present on a planet, and to what extent they are

involved in the planets politics and daily life,

consult the tables below. At each class of world

each branch of the Adeptus Terra is listed with a

dice value. Roll the indicated dice for each Adepta

and consult the ADEPTA PRESENCE table below

to determine the normal everyday presence and

influence that Adepta has on the world. Following

the tables there is a brief explanation of what each

level of presence means.

For purposes of simplicity, the Inquisition and

Adeptus Ministorum are included here as well,

even though they are not strictly branches of the

Adeptus Terra.

SIZE: The size of a world is defined by its

equatorial circumference. The smallest planets mayhave a circumference of only 5,000 kilometres, and

the truly massive planets may reach 500,000

kilometres. (To provide a sense of scale, Holy Terra

itself has a circumference of 40,000 kilometres).

AXIAL TILT: The degree by which a planet

leans to the side on its axis determines how severe

its seasonal variations are.

86-95 Severe (36-45o

)96-00 Extreme (46o+)

The other planetary trait that gets affected by

axial tilt and the resulting seasonal variation is

temperature. A planet with no axial tilt experiences

no change of seasons, with an increasing tilt

causing an increasing variation in seasonal

conditions. The effect this has on the planets

statistics is to cause the temperature to raise in the

summer and drop in the winter. The northern

hemisphere will experience summer while the

southern has its winter, and vice versa.

The table below shows how much the

temperature changes with the seasons. The given

temperature for the planet gets modified by the

shown amount in summer and winter, but stays as

given in autumn and spring (the modifier is applied

to both the max and min temperatures given, so 10to 30 with a +20 modifier would become 10 to 50).

The seasonal modifier may move the temperature

into another bracket on the temperature table

(bitter, cold, chilly.hot roasting, searing), and the

affects of the new bracket then take effect.

to complete one full rotation of its local star. Divide

this number by 365 to see how many Terran years

this is. To determine how many local days make up

a local year, simply multiply the number of days in

the year by 24, then divide that number by the

length of the planets day.

GRAVITY: Most planets that have civilisation

on them have a gravity that is equal to Terran

gravity, or close enough that humanity can easily

adapt to life there.

A standard gravity level is so close to Terran

gravity that humans notice no difference, or one so

slight that they easily adapt.

Light gravity worlds affect a characters ability

to operate normally. On such worlds characters

increase their Agility bonus by 2 for purposes of

determining their movement, add 4 to the total of

their Strength and Toughness bonuses fordetermining encumbrance levels, and add 2 to their

Strength bonus to determine throwing distances. In

addition, all jumping and leaping distances get

doubled.

High gravity worlds affect characters in a

similar, but opposite way. Agility bonuses are

lowered by 2 for determining movement, the total

of Strength and Toughness bonuses loose 4 for

determining encumbrance, and the Strength bonus

has 2 subtracted for determining throwing ranges.

Jumping and leaping distances get halved.

Very light and Very heavy gravity worlds have

all of the modifiers given above doubled: +/-4 to

Agility for movement and Strength for throwing,

+/- 8 to Strength and Toughness total for

encumbrance. Jumping and leaping get quadrupled

or quartered.

96-100 Very Heavy (1.5 to 2)

ATMOSPHERE: The gasses that make up a

planets atmosphere are numerous, and occur invarying degrees and proportions. A detailed

description of a planets atmospheric makeup is not

necessary for gaming purposes; we need only be

concerned with whether or not humans can breathe

easily, and how dangerous the air is if it is not

within the range that is conducive to human

respiration.

A Normal atmosphere supports human life in a

comfortable manner, and breathing is regular and

relaxed in such an environment.

A Bearable atmosphere can be breathed

normally for a short time, but carries a slight

abnormality, will create an unfavourable taste in the

mouth, and will prove fatal if breathed for too long.

Any character subject to such an environment

without a respirator or rebreather can breath

normally for a number of hours equal to their

Toughness bonus, and must then return to a normal

atmosphere (natural or artificial). Being subject to a

bearable atmosphere for any longer will give the

character one fatigue level per hour. Once the

character falls unconscious due to fatigue they will

die one hour later if not provided with proper air to

breathe.


7/14

A Tainted atmosphere is even more dangerous.

A character can only breathe a tainted atmosphere

for a number of minutes equal to their Toughness

bonus, and then gain a fatigue level per minute

longer. Once unconscious due to fatigue, the

character will die one minute later if still in the

tainted atmosphere.

A Poisonous atmosphere is made up of gassesthat are quickly lethal to humans. A character can

only survive unhampered in such conditions for a

number of rounds equal to their Toughness bonus,

and then gain a level of fatigue each round until

unconscious. They will die after one more round in

the poisonous atmosphere.

In a deadly atmosphere, a character will survive

for a number of rounds equal to their Toughness

modifier, gaining a fatigue level each round, and

will then die instantly.

At the GMs discretion, the natives of a planet,

through evolutionary change, may be able to endure

a bearable, tainted or poisonous atmosphere without

penalty.

HYDROSPHERE: The hydrosphere of a

planet is how much water the land and the

atmosphere contain. This can be water vapour in

the air, streams and rivers, lakes, seas and oceans.

A Waterless world is completely deprived of

water.A Parched planet has some water but it is hard

to locate and make use of. Perhaps all of the

planets moisture is vapour in the air which must be

farmed, or held in reservoirs deep underground and

must be mined.

An Arid world has landmasses like deserts,

being mostly dry, but having infrequent spells of

rainfall, and being dotted with oases. There is also

usually a substantial water table underground which

can have wells dug to it. There will be some small

seas and oceans.

A world with an Average hydrosphere gets

frequent rainfall, and has rivers and lakes, seas and

oceans.

A Damp planet has seas and oceans, and land

which gets average rainfall and holds onto its

moisture, making it damp all year.

A Moist world has substantial oceans, a lot of

rainfall and permanently sodden ground.

A Watery world is mostly water, with a few

island landmasses.

An Aquatic planet is completely covered with

water.

TEMPERATURE: The mean temperature of a

planet is one of the most significant deciding

factors on how much shelter and technological

assistance humans require to comfortably survive

there. Temperature is always given as a range, as

there will invariably be variations from equator to

poles, and through the seasons.

Temperature is given as degrees centigrade.

An Average temperature world is one where

humans are comfortable in normal clothing and

need only the most basic of shelters to survive.

Warm and Frosty worlds are those whereprotective clothing most be worn when outside, and

shelters must have power to maintain a controlled

environment inside. If exposed to such and

environment without protective clothing, a

character can withstand it for a number of minutes

equal to their Toughness bonus. Every minute

beyond this will cause the character to gain a level

of fatigue until they fall unconscious, and they will

die after one more minute.

Tepid and Chilly worlds also require protective

clothing and controlled environment shelters.

Exposure to such environments can be tolerated

only for a number of rounds equal to the characters

Toughness bonus, then the character will gain afatigue level each round until they fall unconscious.

One more round of exposure kills the character.

Hot and Cold worlds require extreme

environment protection. The protective clothing

required for such environments are expensive and

cumbersome, and for the inside of a shelter to

provide a normal environment against such

conditions requires a lot of power and the strongest

construction. Anyone unfortunate enough to be

exposed to such an environment will last a number

of rounds equal to their Toughness bonus and will

then die.

Roasting and Bitter conditions cannot be

tolerated by humans, even dressed in the most

extreme protective clothing. Buildings equipped

with huge power-plants and complex equipment to

ward off the environment and make conditions

bearable inside need to be constructed, and

movement must be done briefly and in special

vehicles. Unprotected exposure to these

environments will kill a character instantly.

Searing planets are the most extreme hot

environments imaginable. Only the toughest and

most scientifically advanced materials can

withstand the heat of these places without bursting

into flames.

TERRAIN: Some planets have a single

dominant terrain type, a particular model that

describes all of the land to be found on the planet.

Other planets have more than one terrain present.

Roll on the first table below to determine how

many terrains the planet has, then generate each on

the second table. You can divide a planet betweendifferent terrains by having more than one landmass

with a terrain each, or simply divide a landmass

into regions of each terrain. You could even overlap

and mix different terrains.

Exactly what the terrain will look like will

depend on other factors, like the temperate and

hydrosphere of the planet. You must decide

yourself how the terrain manifests when combined

with the other planetary traits.

CLIMATE: Created by the combined effects of

the planets qualities, like terrain, temperature and

hydrosphere, the climate is a brief description of the

prevalent conditions on the surface of the world.

You will have to look at the contributing factors,

imagine how they will interact, and give a brief

description of what it is like on the planet. If you

want the planet to have climactic variations, maybe

for different regions, or through changing seasons,

describe them here.

NATIVE FLORA AND FAUNA: If you wish,

you can create the details of any native plant andanimal life on the planet. Doing this can breathe

some personality into a planet, bring it alive and

make it distinctive from the millions of other

planets in the Imperium.

COUNTRIES AND CONTINENTS: How is

the planet divided? Is the entire population united

as a single political body, or are there rival and

competitive or friendly and cooperative factions or

countries? Is the entire land of the planet a single

mass, or are there continents divided by oceans?

These are details that you must decide based on the

other features of the planet and the requirements the

planet is to fill in your campaign.

POPULATION: The population of a planet in the

Imperium can vary from a few dozen settlers or

scientists on a frontier world up to the billions on a

hive world.

Note that the Imperium does contain worlds

with a population higher than that possible on the

following table. The reason for the maximum on

this table is that Dark Heresy is set against the

backdrop of the Calixis Sector where the capital of


9/14

Scintilla has, at 25 billion, the largest population in

the sector.

If you are generating a world that is to be set

outside of the Calixis Sector, you may wish to

extend or modify this table to create even larger

populations.

The roll to determine the population of a planetgets two modifiers applied, based on the class and

size of the planet.

SOCIETY: Though all planets of the Imperium

are beholden to the authority of Holy Terra, the

Emperor cares little for how any individual planet

is organised. Different social structures exist, and

even within each of the broad definitions on the

table below there can be variance and variety. You

can define the politics and social structure of the

planet as broadly or as narrowly as you desire or is

required.

A Democracy is a system of government based

on a few definite principles: all people are subject

to the same laws and punishments; no one has anygreater right to something than someone else; there

must be a respect for individual will and freedom;

no person has the right to rule arbitrarily over

others; on matters of important political decisions,

the whole population has a say, votes must be

made, and the majority decision followed; on the

day to day running of the nation a party of

representatives make the decisions and enforce the

laws; these representatives must be voted into their

position by the population, with those who get the

majority vote being given the responsibility.

Usually there must also be three distinct branches

of government for it to be a true democracy; the

legislative, administrative and judicial.

In a Dictatorship one person has absolute

power, their will is law, and they can make and

change rules as they see fit. An absolutist dictator

will often have a group of advisors, but in the end

their decision is final. There will be a government

body to oversee the day to day running of the

society, but the dictator can change, increase or

decrease their power at will. The dictator can be

elected (voted into the position by the population),

hereditary (the position is passed on to the old

rulers child) or tyrannical (the ruler has conquered

or oppressed the people they rule over).

In a Monarchy, there is a monarch, who has the

position through either election or hereditary right,

but who rules according to a written constitution.

There are laws which the monarch must follow, and

rules which restrict and define their power. A

government party exists to oversee the monarch,

which has the power to make rulings based on the

constitution, which can override any decision the

monarch makes which conflicts with the

constitution. The constitution can be amended only

by a majority vote.

In a Military society the planets culture is

either built around a military cause, or there have

been events in its history which caused a great

demand for military action and organisation. Either

way, the society is ruled by the military, and

military rank, instead of noble or bureaucratic rank,is the position of highest political authority.

Everything is arranged and run in a military

fashion.

In a Religious State, either the society was built

around, or because of, a religious body, or events in

its history have brought religious authority to the

fore of all politics. Either way, a religious body is

the areas government and law, and everyone must

follow, or at least never act in defiance of, the rules


10/14

of the religion. The religion in question can either

be a local religion, or Ministorum of the Imperium

or the Machine God of the Adeptus Mechanicus.

An Oligarchy is where there is a small body of

wealthy people, not of noble birth or having

military, religious or bureaucratic rank, who rule

the area. They may be merchants, artisans, or some

other type of guild members, but whatever theirorigins or source of wealth, they keep their

authority only through that wealth and the fact that

they finance the society from their own pockets.

Obviously the types of society on the following

table contain certain options that are more

compatible with certain types of planet than with

others. For example, a forge world will almost

always have a Religious (Machine God) society,

but very few, if any, other worlds will. More than

with any other section of planet generation, the GM

should consider rejecting unsuitable rolls, or simply

selecting the most suitable option.

If the planet has more than one country or

continent, you can even have different society types

striving against each other for dominance.

ECONOMY: The economy of a planet is a

description of how the people of that world manage

their resources and finances. Look at the important

contributing factors form the other aspects of the

world determined in this process (class of world,

population and society in particular), think about

your own ideas for the world and the function you

wish it to fill in your campaign, and note as many

points as you can, or desire, about the planets

economy.

Examples of detail you could give are: What is

the local currency called? Do imports from other

worlds get paid for in cash or simply a trade value

to be swapped directly for exports? How extreme is

the gulf between the poor and the wealthy on the

world? How much does wealth dictate about

lifestyle and opportunities on the world? This is an

example of an area where the GM and players can

go into as much detail as they wish, or simply

create only the bare essential facts.

EXPORTS: Decide what the planet produces

that will be valuable on other planets. The produce

of a planet is traded to merchant captains who ship

it off across the stars.

IMPORTS: Whatever the planet is in need of is

brought to them by the merchant captains and

traded for exports.

CONFLICTS: Decide if there are currently anyviolent conflicts underway on the planet. This could

be a civil war between rival factions (contenders

with equal claim to throne / trade war / general

uprising), a struggle to fight off invading xenos

forces (or even to conquer the native xenos!), a war

against insurgents or terrorists, or any other types of

conflict(s) you care to have taking place on the

world.

This is one of the details about the world that

should be discussed between the GM and players to

create the right type of environment and mood for

your game, or decided on by the GM as a suitable

backdrop to a scenario/campaign idea.

DEFENCES: This is what forces the planet has

to defend itself from enemies, both domestic and

foreign. The forces that can be mustered in defence

of a planet and its settlements come in a few

different forms, which are described below.

Enforcers: The local law enforcers and security

forces.

Militia: Part time soldiers, who have civilian

jobs but can be called upon to fight when required.

Standing Army: The normal full time, fully

trained warriors of the planet. Usually known as the

Planetary Defence Force (PDF).

Armoured Force: Any tanks and APCs.

Titan Force: Some worlds have mighty titan war

machines stationed there permanently.

Private Army/Armies: Wealthy

people/organisations can have their own private

armies.

Naval Force: Ships belonging to the Imperial

Navy that are usually stationed in orbit.

Orbital Station(s): Space stations with defence

weapons, like lasers and missiles.

Missile Silos (planet): Missile silos that can

launch missiles over the surface of the world.

Missile Silos (orbital): Silos with the ability to

launch against ships in orbit.

Defence Lasers: Huge laser batteries that can

fire on orbiting ships.

Mercenary Force: Hired muscle, brought in to

fight for money.

The defence forces present on a world do not

include any Imperial Guard or Navy forces that

may be sent there. They are the planets own

defence forces, always present and alert, and

consisting of local troops.


11/14

To determine what forces are present on a

world, first find the class of world on the tables

below, and the three pieces of information given for

each type of force for that world.

The first bit of information is a percentage

chance of the planet having that type of defence

force present: simply roll a d100, and on a result

equal to or less than the number given, the planethas that type of force present.

The second bit of information is what dice to

roll on the FORCE SIZE table to determine what

size of force of the given type is present on the

world.

The third bit of information is what dice to roll

on the FORCE QUALITY table to determine what

quality that force is, if it is present on the world.

Simply make all of these rolls for each type of

defence force and record the results.

IMPERIAL GUARD RECRUITMENT:Does the world have a tradition of supplying

Imperial Guard regiments? How many regiments

have been founded on the world? Is there anything

about the Guard regiments from this world that

makes them distinctive or noteworthy? These are

details that must be decided by the GM/players,

again to add flavour and distinction to the world.

CONTACT WITH OTHER WORLDS:

Travel between any worlds can be accomplished

through the Immaterium with the proper

preparation and successful navigation, but there

exist established, well known, and more stable warp

routes between planets that see a high exchange oftraffic. Note here if there are any stable warp routes

radiating from the planet, and to what other planets

they lead.
