Sir Drake, from Ultima IX
The Avatar first heard about the Sir Drake's fateful journey to seal the dungeon Destard from the broken Sir Robin, who had cowardly fled Sir Drake's party, and was now drowning his sorrows at the tavern in Britain. The Avatar learned that Sir Drake had sealed himself within the dungeon itself.
Should you wish to join us after we have sealed off Destard, you will need to be able to find the secret entrance, because should we succeed, the main entrance will be unpassable.
The main entrance can be found near the small town of Dawn, close to the column on the west coast of Britain. From the main entrance, look to the east. Atop a snowy mountain to the east and slightly south of the main entrance will be an icy patch that blocks the way into the dungeon.
