From the post:
Among of the most renowned and feared of the forces of Waiqar the Undying are the infamous Death Knights—a unit of undead veteran warriors mounted upon vampiric steeds born from the Mistlands. Death Knights are dangerous foes of the living, their tormented spirits overcome with an intense jealousy for the free will of mortals. To many Death Knights, the act of slaughter is more than just obeying orders—it is the only way they can express their hatred for those not cursed with undeath.
