Xarxes, God of Ancestry and Secret Knowledge
Xarxes began as a scribe to Auri-El and has kept track of all Aldmeri accomplishments, large and small, since the beginning of time. He created his wife, Oghma, from his favorite moments in history. At the end of his quest in Oblivion, Hermaeus Mora claimed that he gave the knowledge inside the Oghma Infinium to Xarxes. Xarxes then gave this knowledge to Mehrunes Dagon with which he wrote the Mysterium Xarxes. It is through those books that he survives.
