Sprite

The tiniest of the fairies, their language is completely impossible for anyone but sprites to understand. They understand other languages, however, making it possible to hire them them via sprite-translators. They’re usually employed as light-givers, though they take payment in completely random things: single coins, bags of hay, mismatched socks. They’re so small it takes several to cart away any one of these items. Not much else is known; they keep to themselves.
