Most NPCs use templates and whatnot, and while there will be some special characters not open to players, players won't be blocked from naming themselves whatever they want or making their character look however they want.
This thread is now about if there are any FAN characters you want added as NPCs. I don't know how much fan-generated (fanfic) content will be done, but if there's anything you want added, post it here.
It doesn't matter how fanciful or "out there" the idea is, if you feel it fits the World of Two Moons, post it. It may or may not go in, but if we don't know about it, it definitely can't.
