Planet Creation

To create a planet, start by picking or rolling on the table below:

1d6	Planet Type
1	Gaian Planet
2	Desert Planet
3	Oceanic Planet
4	Frozen Planet
5	Burning Planet
6	Eyeball Planet

Before moving on to the next section, you should also pick or roll to decide what kind of atmosphere it has:

1d6	Atmosphere	Description
1	Nominal	Made up of a mixture of breathable gases close enough to human standard to be safe without any special equipment.
2	Marginal	Dangerous to breathe, but can be rendered safe with special equipment like rebreathers, filters or pressure masks.
3	Unbreathable	Not poisonous, but doesn’t have the right mixture of gases to be breathable and will cause suffocation.
4	Poisonous	Actively harmful to humans. Whether or not it is breathable, inhalation will cause serious illness or debility.
5	Corrosive	Not only poisonous, but also degrades protective seals and damages delicate equipment over time.
6	Thin	Either completely airless or thin enough that exposure isn’t much better than vacuum.

And what kind of biosphere, if any, is present:

1d6	Biosphere	Description
1	Nonexistent	No biosphere at all, or a microbial biosphere that may or may not interact with human biology.
2	Terran	Whatever biosphere the planet once had has been replaced by human-introduced lifeforms.
3	Miscible	Alien lifeforms that are compatible with human biology - we can eat them, they can eat us.
4	Hostile	Alien lifeforms that are mostly poisonous, radioactive, or otherwise incompatible with human biology.
5	Mutagenic	Alien lifeforms that respond to human settlement, changing rapidly and unpredictably.
6	Delicate	The alien biosphere is easily disrupted by human interference and requires careful ecology.

And finally, what kind of gravity it has:

1d6	Gravity	Description
1	Minimal	Weight is more of a suggestion than a rule. You can launch yourself with ease, and land unharmed from great heights.
2	Low	Everything feels unnervingly light and insubstantial. You feel stronger and can jump further than you’re used to.
3-4	Nominal	Close enough to 1G that you can’t really feel the difference.
5	High	Everything is a little too heavy, every movement feels sluggish, and you tire faster than you’re used to.
6	Crushing	Even standing or walking is difficult, and it feels like you’re wading through mud. Jumping and athletics are almost impossible.

Gaian Planet

A gaian planet is earthlike, with liquid water and perfect conditions for terrestrial life. It usually has indigenous life already.

Desert Planet

A desert planet is arid and desolate, with very little liquid water and vast deserts or tundras covering most or all of its surface.

1d6	Locale	Description
1	Oasis	A place of welcome respite that stands resolute against the desolation of the desert. It is a fragile miracle.
2	Wasteland	A place of lonely emptiness, devoid of life or any of the things you need. Its only purpose is to be endured.
3	Barrier	A daunting obstacle or a natural fortress, depending on your perspective. It looms in your path and blocks the way forward.
4	Warren	A place where the desert gives way to a tangled and treacherous realm. It can be a source of shelter and shade, or of secrets and peril.
5	Ruin	A fallen remnant that was once a place where people or creatures thrived. It’s filled with the things they left behind.
6	Fell	An eerie place, haunted by silence and strangeness. It’s a place where your mind plays tricks on you, and every footstep feels too loud.

When visiting this planet for the first time, choose 1 or 2 features that make it unique:

Vast craters left by ancient asteroid impacts, scarring and pitting the surface.
Ancient fossils and the eerie remains of petrified forests, hinting at an ancient past.
Temperate little pockets with their own weather systems, like gigantic oases in the desert.
An unstable ring system encircles the planet and bombards the desert with frequent meteor showers.
The planet has vast reserves of water, but they are trapped in the form of polar ice caps.
Vast storms that cover hundreds of kilometers sweep the entire planet for weeks at a time.

When entering a new locale, choose a few aesthetic touchstones that define the area:

A sea of undulating dunes that vanishes into the horizon.
A barren expanse of baked earth, riddled with cracks and crevices.
A stony pavement dotted with eerie wind-carved rockforms that jut haphazardly from the ground.
A frigid tundra of hard-packed snow, cold dead rock and permafrost as hard as concrete.
A shimmering salt flat that shines blazing white in the desert sun.
Towering plateaus and mountains that shimmer on the distant horizon.
Scurrying creatures darting around in the shade.
The bones or withered husks of people, creatures or machines that did not survive their journey.
Crystalline fragments that glitter in the sunlight like a sea of stars.
Expanses of glittering ice, crystal or glass which blaze like a white-hot sheet in the desert sun.
Shaded caves where precious water trickles and gathers.
Lava tubes and caves that connect the desert to intricate subterranean caverns.
An enormous sinkhole punched into the surface of the desert, exposing vast caverns below.

Oceanic Planet

An oceanic planet is covered by a liquid, world-spanning ocean. Dry land is scarce, ephemeral, or even nonexistent.

Frozen Planet

A frozen planet has a surface covered by frozen oceans of ice and frost. It might go all the way down the core, or it might give way to subsurface oceans.

Eyeball Planet

An eyeball planet is tidally locked, burning on the bright side and frozen on the dark side. A temperate “twilight zone” lies between them.
