I don't even know why, but several people loved my OC. He wasn't even a well-developed character, and he only appeared in a one-shot anyway. Maybe because the story still focused more on the canon character than on the OC. *shrug*
Forgotten Realms fandom is full of OCs, simply because it's also (or should I say, mainly) the setting of an RPG, so many people post stories about their own RPG characters and adventures. It's annoying when you're looking for fic about the characters from the books.
