Nathaniel Moorehead

Nathaniel Moorhead is one of the Ten Pirates of Hawkins, and had one piece of the Treasure Map of Hawkins, which is needed in Ultima VI.

Moorhead died prior to Ultima VI, after living the life of a honest man at Empath Abbey, having being lost at sea one day. He had left behind a locket, wrapped into part of a cloth map which he'd told his wife could make her rich. The locket with the map piece however got stolen from his widow, Sylaina by Arturos of the gypsies. The Avatar had to buy the locket from them to get the map piece.

The Ultima 6 Project
In The Ultima 6 Project, his past was expanded upon, and Sylaina mentioned her late husband's buddies Dagan, Bast and Sy. She suspected all three of them to be connected somehow to her husband's past. The Avatar could find these three pretending to be a militia group, but actually robbing unsuspecting travelers.
