Lord Indoril Nerevar, also called Saint Nerevar Moon-and-Star, the Champion of Azura, the Hero of Red Mountain, and Godkiller, was the Chimer
King of Resdayn (modern-day Morrowind). As the Hortator, or Great Ashkhan,1 of the united Chimer people, he forged an alliance with the Dwemer, and he was one of the founders of the First Council, uniting all the people of Resdayn for
the first time in 1E 416. Nerevar then took on the title of "First Councilor". The alliance
eventually broke down, leading to the War of the First Council. At the climactic Battle of Red Mountain circa 1E 700, Nerevar led the Chimer to victory, though he died shortly after the battle under disputed
circumstances.
Under the Tribunal Temple, he was known as the Herald of the Triune Way. Ashlander prophecies of his "rebirth" as the Nerevarine and heroic return to Morrowind fueled the creation of the Nerevarine Cult. St. Nerevar the Captain, patron of Warriors and Statesmen, became one of the foremost saints of the Dunmeri faith, along with his wife, Almalexia
the Warden, Lord Sotha Sil the Magus, Lord Vivec the Poet, and Saint Veloth the Pilgrim. Nerevar became the patron saint of House Redoran.
