Sauron's physical manifestation was destroyed in the ruin of Númenor. As a Maia, his spirit returned to Middle-earth, though he was no longer able to take the fair form he had once had. The loyal Númenóreans reached the shores of Middle-earth. Among these survivors were Elendil, their leader and a descendant of Elros, and his sons Isildur and Anárion, who had saved a seedling from Númenor's white tree, the ancestor of that of Gondor. They founded two kingdoms: Arnor in the north and Gondor in the south. Elendil reigned as High King of both kingdoms, but committed the rule of Gondor jointly to Isildur and Anárion. The power of the kingdoms in exile was greatly diminished from that of Númenor, yet very great it seemed to the wild men of Middle-earth.
