A vargul member of the Ymirjar.
The Ymirjar are the elite warrior caste of the Lich King, the victorious vrykul in the battle of ascendance at Jotunheim. They inhabit the city of Ymirheim in the center of Icecrown.
Those deemed worthy by the Lich King are granted immortality in undeath after their victory at the battle for ascendance and become Ymirjar, while the losers become cursed vargul.
Their ranks are composed of frost vrykul, normal vrykul, and flesh giants. Some vargul can rise above their station through vigorous effort and also become Ymirjar.
