Varghulfs are those powerful yet devolved Vampire lords that have since succumbed themselves willingly to their most primal surges, turning their once human bodies into a creature larger and far more powerful in body, but weaker in mind. Within most Vampires, there is a constant animalistic urge that can occassionally drive a Vampire to bouts of uncommon savagery and bloodlust. Such urges are what forces a Vampire to suck the blood of the living. Most Vampires who still want to cling to their sanity are often known to seek control of this side of their existence, and in keeping to their trappings of aristocracy and nobility.[1a]
