Imps

Imps are a minor breed of daemons, similar in size to mongbats and typically possessed of a mischievous temperament. They appear in  Ultima Underworld I and  Ultima Underworld II

Description
Imps are intelligent beings found in only a few remote underground locations in Britannia, although they are prevalent on other worlds. Frequently hostile, these green pests tend to attack unwary adventurers while in flight, casting magical bolts at their targets from afar.

On some rare occasions, imps will deign to speak with or even assist human beings, although they are noted for their dark sense of humor and puckish nature. Such creatures have both helped and hindered the Avatar in the course of their questing, although their motives as a race remain inscrutable.

Notable Examples

 * The Listener: a minion of the Guardian sent to spy on Castle Britannia during Ultima Underworld II
 * Spiritual Imp: a native to the Ethereal Void in Ultima Underworld II who delights in mocking those who attempt to thwart the Guardian's magics
