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 in his/her quest to defeat the wizard Tyball by providing him/her with a magical crown which helped the Avatar navigate an otherwise invisible maze in the Stygian Abyss. When the Guardian encased Castle British in a black rock gem, an imp spied on the Castle's inhabitants on the Guardian's behalf.
