I've got the idea to create an interstellar fantasy universe (I've never played Spelljammer or own any of the books, but I've seen some of the material). Humans, elves, dwarves, and some others have formed a society that rules or influences about 1/4 of the galaxy. the Drakine, who in my universe are stoic, honor-obsessed warriors, have formed an uneasy alliance with them (yes, like the Klingons). As you can see, Star Trek has influenced me a lot.
I'm trying create some of the other major interstellar civilisations, especially villanous ones. I've come up with two, the Gol (magickal version of the Borg) and the the Ythgarl-oloom (somehwat like the Jophur from Uplift, but with a more Lovecraftian bent). And this is before I get to the ominous task of worlds-building.
has anyone ever done this sort of thing before? some help would be appreciated.
