A few people from other projects.
Edison, from the horror story I'm currently working on.
Vincent Detroit, from a cyberpunk story I stumbled into.
A viking named Sven.
Er. Well, see... okay. The other story I'm writing at the moment, called Dark Lord Seeks Friendship, Maybe More, came about because I was annoyed at the excessive amount of fantasy stories featuring a "dark lord" with the personality of a sheet of paper. You have to figure that if a Dark Lord came to power and is still in power, there have to be good reasons for the following they have-- and while there are stories that have been written addressing this issue, I too wanted to try my version of "Dark Lord has actual personality and a life outside of destroying all that is good."
So. Dark Lord Seeks Friendship, Maybe More, in which the Dark Lord is a little lonely and so his minions try to set him up on dates, with lighthearted romantic comedy sorts of results. Only, you know, a romantic comedy with a Dark Lord as the protagonist. Oh, it also features Sven from the drawing above this one.
Yes, you had to know all about that before I tell you that I pretty much just took my design for Collin and used that for the Dark Lord. Collin naturally makes a good evil overlord.
