Nerevar

Nerevar was a Chimer king and hortator of ancient Resdayn. Sotha Sil, Vivec, and Voryn Dagoth were his trusted advisors and friends, and Almalexia was his wife. He was later murdered during the War of the First Council with the Dwemer king Dumac, though it is believed he will one day be reincarnated as the Nerevarine, with some believing that to be Chodala. A projection of him can be found at the Elegiac Replication above a pedestal with a plaque commemorating his memory.
