The cruel leader of the Black Tide, Athum (from Q. Athumo: "Colleague") was a concentrated and potent source of evil in the Twin Nations. Athum had been terrorizing the night with his minions for hundreds of years.
Originally, Athum was an Elven spy sent by Sauron in the Second Age to watch the southern shores of Middle-earth. He was solitary until he formed the Tide in T.A. 1270. He later accidentally fused his spirit with a demon. The transformation left him slightly less sane than he had been. He had rarely left his monastery since, because he hated his dreadful appearance. Athum was hopelessly evil, however.
Athum stood 6'8" tall. He had a demonic appearance, although the presence of his elven blood could still be noticed. His hair was black, as were his eyes. He had grey bat-wings stretching outward from his back. He was a frightening sight, to say the least.
