Never thought I'd have to say this, but Silas is my furry OC, so pls do not steal. Particularly since he wasn't and isn't just an online persona character, the webcomic I'm about to write is specifically about him, and I'd like to have some (Not all) of his ties with this website cut short. I'd prefer it if you didn't put him in anything that you don't publish on here.
I don't really have any more copyright power than anyone else here does, so I can't and won't come after you for doing it or anything, but I would really appreciate it if you changed his name. Silas's name/face association holds a sort of sentimental value for me after all these years, and It'd feel really shitty to have to change his name in any future "Real Writing" works containing him just to avoid confusion and legal tieups.
