Imps

Imps are small, flying, intelligent monsters found only in the Ultima Underworld games. They fight by throwing magical bolts. In one instance, an imp assisted the Avatar to defeat the wizard Tyball by providing a magical crown which helped the Avatar navigate an otherwise invisible maze in the Stygian Abyss. When the Guardian encased Castle Britannia in a black rock gem, an imp spied on the Castle's inhabitants on the Guardian's behalf.
