Lorkhan

Lorkhan, also known as Shezarr or Shor, was one of the Aedra prior to Nirn and Mundus. He played a major role in it's creation, devoted so much to it that he gave up his life for its creation. It is said that he gave up his life and either the other Aedra willingly devoted themselves or he tricked them into revoking their divinity for the creation of Nirn.

Origin
It is written that Sithis begat Lorkhan, with one intention: to destroy the universe. Sithis did this because the Aedra had enslaved all of Sithis' creations. This is unknown to be true, although the Dark Brotherhood tend to lean toward this conjecture as they are Sithis' followers.

History
Lorkhan, along with Akatosh, appear in every form of mythology on Nirn. Although that much can be said, not all opinions of him render him a divine god. For instance, the races of Men on Nirn revere him as the holy creator of everything. The Mer, however, do not take so kindly to this opinion, rather choosing to believe that he is the reason for their mortality as he tricked the other Aedra to sacrifice their divinity for Nirn. The only variation to this is that the Dunmer believe their mortality is a test of their willpower and strength and ultimately they will gain back their immortality.
