the Jester
Legend
2) Psycho balance enforcer. Too much happiness in the world? Kill some kittens! Too much misery? Push an evil-doer off a bridge! Too many laws? Burn down a city! Not enough laws? Burn down a forest! Has this person ever existed outside of D&D or D&D-derived fiction? I very much doubt it.
EDIT - Though I am kind of narrowing my eyes at Michael Moorcock here, as I seem to recall one of his characters being along these lines.
And don't forget the dwarves of Narnia in the Lion, the Witch and the Wardrobe.
