Ultima VI: The False Prophet/Map piece in Dungeon Shame

Homer said: "Old Ybarra said he was headed for the dungeon Shame, looking for more treasure."

Dungeon entrance
The dungeon entrance is located in the mountains between Britain and Skara Brae.

The only way to get there is by water, rowing up the river passing between Skara Brae and Empath Abbey. You can borrow the skiff in Skara Brae using the "Vanish" and "Reappear" spells.

Dungeon walkthrough
''According to the Ultima philosophy, Shame is the opposite of Honor. Honor comes from Truth and Courage, therefore Shame comes from Falsehood and Cowardice.''
