This is Settra the Imperishable on display at Warhammer World.
Feared by all in both life and death, Settra the Imperishable is the lord of Khemri, a ruthless tyrant whose appetite for conquest cannot be satisfied, no matter how many lands he invades or people he subjugates. Settra now busies himself with reconquering the lands that were once his – lands that, in his long absence, have fallen into the hands of upstart lords and bickering emperors. In time, all will bend the knee before the supreme ruler of Nehekhara once more.
