Like their Southern Kalimdor siblings, the magical beasts called vampire bats of Zul'Aman have always savored the frenzied turmoil of battle. This chaotic disposition has naturally aligned them with the Forsaken, who continue their struggle against the Lich King's Scourge while maintaining a tense alliance with the Horde. In addition to ferrying those who pay for their service throughout Lordaeron, the vampire bats also act as scouts for the Dark Lady.
