Malacath

Malacath (also known as Malak, Orkey, or Mauloch ) is a Daedric Prince whose sphere is the patronage of the spurned and ostracized, the keeper of the Sworn Oath, and the Bloody Curse. His known artifacts are the war-hammer Volendrung and a one-handed mace known as Scourge. Malacath enjoys watching mortals fight and cares a great deal about honor. He also cares about his followers as well as the Orsimer people. Giving his Aedric origins, he has been sort of ostracized from the other Daedric Princes. His plane of Oblivion is called the Ashpit, which is where loyal Orsimer believe they go when they die.

Origins
During the exodus of the Chimer, when the Chimer denounced all ties to the Aldmer, the Aldmer fought alongside the warrior god Trinimac against their elven brethren.

But the Daedric Prince Boethia fought on the side of the Chimer.

Trinimac confronted Boethia, and a fearsome battle ensued. In the end, Boethia emerged victor, having devoured Trinimac.

Boethia then spoke in the voice of Trinimac, to rally the Chimer and strike fear into the hearts of the Aldmer. Trinimac was twisted into the cruel Malacath, and his followers into the Orsimer.
