Fire Elementals

Fire elementals are living incarnations of elemental flame which may be found manifested on a variety of worlds. They appear in Ultima Underworld I and II as well as in Ultima VII Part Two

Description
Fire elementals have been found in the realms Britannia, Rhiannon and Serpent Isle and often congregate near volcanic activity and other sources of heat conductive to their element. Possessed of a fury as biting as the flame they embody, these deadly creatures attack their opponents with the living fires of their own bodies and are unlikely to relent once provoked. It should be noted, however, that they have markedly poor vision, and may be avoided or outrun by a crafty adventurer.

While the difference appears to be purely cosmetic, there is some variation in the appearance of fire elementals on different planes. The elementals of Britannia and Rhiannon have a flickering and intangible visage, looking very much like normal spouts of flame aside from their glowering faces. On Serpent Isle, however, fire elementals take a vaguely humanoid shape and leave behind ashen corpse-like husks when killed.
