This article or section contains lore taken from the Warcraft manga or comics.

The Mark of Kathra'Natir is a powerful corrupting curse. Vendellin Soulfire cast this spell on Valeera Sanguinar during her journey to Stormwind with Varian Wrynn, Broll Bearmantle and Thargas Anvilmar.

Once the curse is cast, the subject becomes the host of the dreadlord Kathra'Natir.

This article or section includes speculation, observations or opinions possibly supported by lore or by Blizzard officials. It should not be taken as representing official lore.

The spell may have something to do with Katrana Prestor, because Vendellin was hired by her and because the name "Kathra'Natir" looks like another form of expressing the name "Katrana" (Kathra'Natir).
