Goeth

Goeth is the member of the Great Council representing Jhelom.

When meeting Goeth in Ultima V, his speech was very bizarre as he only spoke in random words backwards, and didn't understand anything the Avatar asked. So the Avatar asked the other citizens of Jhelom about his speech, and was told that his bad treatment by the Oppression, who tried to extract the word of power, and the isolation on Jhelom had made Goeth go totally mad, twisting his speech. Goeth was free because the Oppression had lost any hope of getting the word out of him.

However, the Avatar now had the vital clue and asked everything backwards, thus managing to get through to Goeth, who then revealed the word for the dungeon Destard. He also revealed how to excavate Moonstones, something he'd learned before being arrested.
