Goeth

Goeth is the member of the great Council representing Jhelom.

When meeting Goeath in Ultima V, his speech was very bizarre as he said random words backwards and also didn't understand anything the Avatar asked. So the Avatar listened around and got the story that the bad treatment by the Oppression (in order to get the word of power) and the isolation on Jhelom had made Goeth go totally mad, making him twist around words in his speech. He was free to go, since the Opression obiously had lost any hope to get 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 did indeed reveal the word for the dungeon Destard. He also revealed how to excarvate the Moonstones, something he'd found out before being arrested.
