Gnomes: Little men born of earth. They can only see clearly in darkness. Ride moles and love arts and crafts.
Goblins: Despicable little things with features of all kinds. They are obviously trying to curse you. Yes, they are selling something. No, they won't go away.
Elves: Beautiful, courtly, otherworldly. There is something up with elves, something strange, everyone can tell.
Birds: Diverse and flighty, thin boned. They've been convinced they should try to be real people, whatever that means
