Imps

Imps are small, flying, intelligent monsters found only in the Ultima Underworld games. Appearing to be some kind of simian-daemonic hybrid, these green pests fight by hurling magical bolts at their opponents, but are easily defeated if drawn into melee range.

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 blackrock gem, an imp spied on the Castle's inhabitants on the Guardian's behalf.
