I'm sorry if this was mentioned somewhere, but are fandom OCs okay? My guy is from the Dragon Age universe. Obviously I would remove any interaction with cannon characters from that universe, which I never really consider "cannon" for him anyway.

So he'd just be from an established fandom universe, while being an OC. Cool? Not cool?

OH ALSO:

He's possessed, kind of. More like fused with a powerful demon. Of course I would be reasonable with power caps, but is he allowed to keep his dragon-demon if so?

Thank you :)
