Lucius the Cruel is a unique, named undead and a minor antagonist during the Worgen starter quest in World of Warcraft.

Lucius is part of a Forsaken invasion upon Gilneas and like many of his kind specialized in stealth and assassination tactics by which to terrorize the population.

Lucius devised a particularly inventive means to lure victims to their demise by capturing Grandma Wahl's cat, Chance, and using it as bait.

However when Grandma Wahl asked the player to find her "lost" cat Lucius made a fatal mistake as he ambushed the hero and claimed he would keep Chance for future use as bait : this prompted an enraged Grandma Wahl to literally charge into the battlefield, transforming into a Worgen and aiding in killing Lucius in order to save her beloved pet.
