If you would like, you can introduce him in both threads. A character sheet of sorts would be a good idea, if only to keep track of stuff.
That way, you can describe your character and whatnot here, and also in the other thread. I find that having a reference is always a good idea. Of course, others may disagree. *shrug*. I don't particually mind either way. After all, as stated above, this isnt't exactly a serious game.
What did you have in mind?
