These ancient, evil behemoths were once the mighty kings of the subterranean spider kingdom of Azjol-Nerub. Though the Nerubians fell before the wrath of the Lich King during the fabled War of the Spider, the insidious Crypt Lords were swayed over to the Lich King's ranks and granted considerable power and the immortality of undeath. Now the giant, thundering beasts serve as the Lich King's mightiest warriors and the guardians of the Scourge's holdings in Northrend.
