Trian, from Ultima V: Lazarus
After talking to Goeth had failed, the Avatar listened around. Talking with Trian, the man first spoke of Courage and that his friend Thorne often visits the shrines. Then finally the Avatar asked about dungeon Destard, expressing the wish to explore it.
Trian thought of the Avatar as suicidal, adding that it was illegal. He however still gave the hint, that saying things backwards to Goeth should do the trick to get the word out of him. It did indeed.
