Feel free to take a sneaky peak here: The Topaz Galaxy. There are some descriptions of the already existing world/galaxy, but nobody to take on any of the vital leadership roles necessary to push any large plot. I want some evil baddies with ambitious, outrageous, and heinous goals! However, there needs to be some good monarchies too to combat them. It would be nice to see some blind siding, war, and whatnot.
There are also two roles in the human race that need to be filled. None of these roles are super descriptive, so they're totally open to basically whatever you would like, as long as they are persons of political power, basically.
It is primarily sci-fi with some side plots existing on an underdeveloped medieval magic world that may or may not suffer from sci-fi turmoil at some point. Sort of hoping the baddies will create some treacherous and sinister plots. If you're interested, just shoot me a message!
