Shadows in Space
This is more World Creation.
Things are being simplified for this, since not all of us have the background in astrophysics, astronomy, or other such things.
A world is described by a name, a brief description, and then three “World Aspects.” From the World Aspects, three skills are chosen, and a character from that world gains a specialty in ONE of those three skills.
(More worlds will be added as I think of more.)
