Sethys

Sethys is a follower of Chaos who was left behind on the Serpent Isle after the War of Imbalance.

The Avatar discovered him in Ultima VII Part Two in the Temple of Tolerance, where he had been kept alive since the war. He told the Avatar how he had lost his key for the drawbridge. Later, when the Avatar needed to summon the Chaos Hierophant, Sethys offered his help. However, walking out of the temple caused him to age rapidly, and he barely managed to tell the Avatar where to find his master's body and that the Eye of the Serpent was needed to summon him, before perishing.

The Avatar took the Eye and used it to summon the Chaos Hierophant, who after speaking with the Avatar, escaped to the void.
