Driven by a desire to reclaim his lost power, Tiriel wanders through a desolate landscape, encountering various figures who represent different aspects of his own failed legacy. His objective is to assert dominance over his progeny, yet he is constantly thwarted by the consequences of his past cruelty and the shifting nature of his reality.
