If you're open to OC, I've been trying to dip my toes into this fandom for the first time recently, with minimal success. I've got the strings of a history and bio for an OC put together (though not posted) and am entirely flexible when it comes to putting together someone different. As far as Fandom players go, I could (and have been considering) trying my hand at a Remus. World building and open communication are my favorite things really, so I'm not shy about those at all. Character Development > All else really.
If you'd care to brainstorm, do let me know. If not, I wish you the best of luck on your search!
