Elf

'' 'This creature's skin has a very pale complexion. You also notice his pointy ears. Do not mistake them for vampires! The elves are rather sympathetic. They also seem quite eager to sell you their wares.'''

Elves are the shopkeepers in the Dungeon of Doom. The are normally found in enclosed rooms, but players have reported finding them wandering around the dungeon (this is apparently a bug).

Either way, they are passive and will never harm you.
