i have a pretty developed universe for the sci-fi prompt actually! it involves a combination of magic and technology, particularly a slant towards multiple dimensions/eldritch horrors in space rather than in the ocean or darkness. the main character i have for that universe is a guy who was the face of a commercial-military complex and ended up venturing so far into space that he got somewhat possessed and now can channel voices/visions. lots of space adventuring and doomsday prophesying ensues, etc. he's still cheery and friendly so he can get along with most people though! maybe would be fun with klaus?

Q is pretty easy to play with! if you have any characters that might end up in a secret agency or needing other "tech support" he's easy to throw in.
