Richard

A strange prisoner named Richard can be found in the prison of Castle Britannia in Ultima IX.

The Avatar was told upon arriving in the jail that there were many unsavory character within, but that one character especially was a complete loon. When the Avatar reached the appropriate cell, the prisoner claimed to be the true Lord British, and that he had been improperly imprisoned. He even claimed that his friend Shamino, whom the prisoner claimed was standing beside him, would vouch for his freedom.

Trivia
