Bonn

Bonn is one of the Ten Pirates of Hawkins, and has one piece of the Treasure Map of Hawkins, which is needed in Ultima VI.

Description
Bonn had shipwrecked on Dagger Isle, not far from the Shrine of Honesty, only a short time after killing Hawkins. The years in total isolation on the island had caused him to become totally insane. When the Avatar found him, he had just thrown his shoes into the sea fearing the Avatar's theft of his footwear, and complained of the constant buzzing of bees within his skull. When asked about Hawkin's map, Bonn admitted having it in his possession, but would not reveal its location to the Avatar, only mentioning his basement, his "future grave". Down there, the map was found.
