Appearance: Varks have heads of birds and the bodies of men and women. The one in Zarsthor's Bane was capable of flying over short distances, though whether she had true wings or just flapped her arms is unclear. The ones in Horn Crown appear to be able to fly and Sassfang in The Warding of the Witch World also travelled in extended leaps aided by her winged arms.
Life Span: The lifespan of a Vark is unmentioned.
Power: In Zarsthor's Bane the bird-woman seems to be able to control some large, black birds. Varks seem able to continue to fight even if dismembered or beheaded. The blood of a Vark is dangerous to the living and seems to be acidic and venomous.
Other: The number of Varks seem to be dwindling. An Dark Old One adept of their race appears in Horn Crown allied with Raidhan and Cuntif. The one in The Warding of the Witch World is named Sassfang and may be the same Vark woman to appear in Zarsthor's Bane.1.
