Faeries

Faeries are much like bees in the magical world. They fester in a hive, spreading out and pestering the world individually, flying back to their nest to share tidbits of news from the wider world with their sisters.

Sprites are the same, only wingless, and like ants in a hill.

Infestations of these have taken root on the hills surrounding the Isle of Avalon, and Mortimer has a run-in with an angry little faerie who has an attitude and tries to get revenge.
