Arcanites
From Age of Sigmar - Lexicanum
The Arcanites are a group that fought the Bloodwrought warband over the dominion of the Beastplains, in the Gargantua Ridge. They wore feathered war-masks. Their leader was sorcerer-king that was slain by the warband leader Ghaar'eth. They were slaughtered and their bodies would be consumed in the dark feast if not for the arrival of a storm. [1]
