A bit of UESPWiki information: The Shezarrines are a group of famed heroes and avatars throughout history who are suspected to bear some connection with each other and http://www.uesp.net/wiki/Lore:Lorkhan. They are named after http://www.uesp.net/wiki/Lore:Shezarr, a Cyrodilic version of Lorkhan introduced as a "watered down" version of http://www.uesp.net/wiki/Lore:Shor during the creation of the http://www.uesp.net/wiki/Lore:Eight_Divines.

Shezarr, God of Man
Cyrodilic version of http://www.uesp.net/wiki/Lore:Lorkhan, a synthesis of Nordic Shor and Aldmeri Auriel. His importance suffered when http://www.uesp.net/wiki/Lore:Akatosh came to the fore of Nibenay religion. Shezarr was the spirit behind all human undertaking, especially against http://www.uesp.net/wiki/Lore:Aldmer aggression. He is sometimes associated with the founding of the first Cyrodilic battlemages. In the present age of racial tolerance, Shezarr is all but forgotten. In 1E 266 the lost Shezarr, the missing sibling god of the http://www.uesp.net/wiki/Lore:Eight_Divines, arrived at the http://www.uesp.net/wiki/Lore:White_Gold_Tower in the http://www.uesp.net/wiki/Lore:Imperial_City and transformed the dying http://www.uesp.net/wiki/Lore:Alessia into the first of the Cyrodilic saints becoming the first gem in the Cyrodilic http://www.uesp.net/wiki/Lore:Amulet_of_Kings.

Or could he be a next son of Kyne like Morihaus?
