Single-player campaign Sacrifices single-player campaign begins with a meeting between the protagonist Eldred and the blind seer Mithras on a war-torn world. Through voiceovers and cut scenes rendered by the game engine, Eldred recounts to Mithras his background and the events that led to the world's current state. Eldred was a tyrannical emperor who ruled over the world of Jhera. However, his days of rule were numbered: his subjects were rebelling, and his enemies gathered at the borders of his realm.
