Morchella

Morchella is one of the Ten Pirates of Hawkins, who now lives in Serpent's Hold in Ultima VI.

Description
After killing Hawkins, she moved to Serpent's Hold, where the Avatar found her. Morchella claimed to be an honest sailor, and not a pirate, telling the hero that she had sailed with Lord British and Captain Johne. Lord British, she said, walked with a limp while Johne had supposedly once tried to marry her. She was willing to give up her piece of Hawkin's map as long as the Avatar gave her a magic shield, asserting that she hoped to give it to Caradon to enter the Order of the Silver Serpent. The deal was made, and the Avatar acquired the map piece. Morchella then decided to keep the shield for herself.

The Ultima 6 Project
In The Ultima 6 Project, Morchella required a special shield representing the Order of the Silver Serpent, and wasn't content with any ordinary magic heater.
