Void Terror

A Void Terror, also called a Void Hound is an enormous and extremely powerful Demon. Void Terrors are massive creatures that possess a nearly unlimited source of magical energy. Despite their lack of sapience, Void Terrors are considered Greater Demons in the Burning Legion's infernal hierarchy for their incredible power. They are hideous Demons well characterized by their appearance, appearing as an enormous, canid creature with two heads, each with a cyclopean eye, dark blue scales and multiple eye stalks sprouting from their back.

Void Terrors are rare Demons and their vast reserves of magical energy make them extremely valuable to any who happen to be in custody of one. Most infamous of the Void Terrors was the Demon Immol'thar, who was bound by the Highborne noble house of Shen'dralar. Under the Shen'dralar's captivity, Immol'thar was capable of providing power and energy for the entire Highborne city of Eldre'thalas for Ten Thousand years before his power began to wane. Void Terrors are suspected to have the ability to phase through the Void, leading to the misconception that they are creatures native to that plane, instead of the Twisting Nether. Void Terrors are true demons, however, yet their infrequent appearances and even more infrequent defeats has made little information on them available.
