The Frostrager class in Valhalla denotes a type of unit representing members of barbarian tribes of Eberron whose ferocity and rage impress and terrify even their fellow barbarians. Typically they are members of the tribes that inhabit the Frostfell, a region that lies at the northern extreme of the world, separated by the Bitter Sea from the continent of Khorvaire. Vydar is the only Valkyrie that has recieved visions of this class unit, this type represented by the character Evar Scarcarver . Considering his reclusive nature and hidden agenda, Vydar must have summoned Evar for the sake of maintaining his hold over his portion of the Underdark.
