System Generation

I have used Stellaris as a good jumping off point for things one might encounter whilst traversing the stars! Go check out that amazing game by Paradox Interactive!

Gravity Wells

The First component of any system is the gravity mass that holds a system together. Be it a star or a black hole, one does not have a system without such a celestial body.

Gravity Wells

1-2	Class B
3-4	Class A
5-6	Class F
7-8	Class G
9-10	Class K
11-12	Class M
13	Pulsar
14	Black Hole
15	White Hole
16	Neutron Star
17	Rogue System
18	Uncanny
19-20	Binary - Roll Twice

Uncanny: an example might be a strange star event that changes its color and size or a gravity effect around a single sliver of light rather than a whole star.

Number of Masses

Within a gravity well, any number of celestial bodies may take up a permanent or temporary orbit.

Number of Masses

[["1-4","1d4"],["5-8","1d6"],["9-12","2d6"],["13-16","2d8"],["17-20","3d8"]] Roll the Dice

1-4	1d4
5-8	1d6
9-12	2d6
13-16	2d8
17-20	3d8

Type

There are many types of celestial bodies, some habitable, some less-so, most are useful and chalkfull of resources.

Mass Type

[["1-14","Inhospitable"],["15-16","Hospitable"],["17","Artificial Structures"],["18-20","Roll twice, the results share an orbit"]] Roll the Dice

1-14	Inhospitable
15-16	Hospitable
17	Artificial Structures
18-20	Roll twice, the results share an orbit

Inhospitable

From asteroids to toxic worlds, there are many planets that are less than hospitable. An inhospitasble planet is a celestial body that has no natural atmosphere or ability to contain conventional life.

Inhospitable

[["1-2","Asteroid"],["3-4","Asteroid, Ice"],["5-6","Asteroid, Crystalline"],["7-8","Barren World"],["9-10","Barren World, Cold"],["11-12","Frozen World"],["13-14","Gas Giant"],["15-16","Molten World"],["17-18","Toxic World"],["19-20","Uncanny"]] Roll the Dice

1-2	Asteroid
3-4	Asteroid, Ice
5-6	Asteroid, Crystalline
7-8	Barren World
9-10	Barren World, Cold
11-12	Frozen World
13-14	Gas Giant
15-16	Molten World
17-18	Toxic World
19-20	Uncanny

Uncanny: An example might be a mass made of a strange gelation.

Hospitable

What every intrepid explorer hopes to find around any star is a new, uninhabited hospitable world with which to stake a claim. A world with life on it may provide the limitless potential to the galaxy in the form of food, drugs, genetic diversity, and, most of all, a place for people to live.

Habitable

[["1-2","Arid"],["3-4","Desert"],["5-6","Savanna"],["7-8","Alpine"],["9-10","Arctic"],["11-12","Tundra"],["13-14","Continental"],["15-16","Ocean"],["17-18","Tropical"],["19-20","Uncanny"]] Roll the Dice

1-2	Arid
3-4	Desert
5-6	Savanna
7-8	Alpine
9-10	Arctic
11-12	Tundra
13-14	Continental
15-16	Ocean
17-18	Tropical
19-20	Uncanny

Uncanny: An example might be a whole planet mass being composed of one massive tangle of roots.

Artificial

Not all masses in a gravity well are natural. Some are constructions by intelligent beings that are here to fulfill a set purpose.

Artificial

1-2	Mining Habitat
3-4	Trade Station
5-6	Way Station
7-8	Military Station
9-10	Permanent Colony
11-12	Research Station
13-14	Solar Stations
15-16	Agri-Disk
17-18	Tax Dodge
19-20	Uncanny

Uncanny: An example might be something stepping in and out of Hydem Space.
