Felhounds, or fel hounds, are demon hounds used by the pit lords to sniff out sources of magic wherever they can be found. Felhounds, who feed upon magic itself, are fond of draining the energies of hapless wizards and then ripping their bodies to shreds.
Felhounds are demonic hounds that feed on magic; they can sense the presence of nearby magic and hunt spellcasters unerringly. This red-skinned creature looks vaguely like a hound — though one with a massive, toothy head that makes up nearly a third of its length. Great horns jut out above its solid white eyes. Their powerful jaws are huge and filled with slender teeth. Their eyes are weak; to get around, felhounds rely on their ability to sense magic. This sense is also how they track their prey. Felhounds are pit lords' personal hunting hounds, starved for both blood and arcane energy. Pit lords grow felhounds somewhere in the Twisting Nether. Felhounds do not speak, though they understand Eredun. Felhounds treat spellcasters, particularly arcane spellcasters, as layered desserts with meat on the outside and magic on the inside. Less magical characters are worth notice only if they have damaged a felhound.
Felhounds look very much a Peace Hound from the comic series Elfquest. They also ressemble zerglings from Starcraft.
