"Sentri is a fighter and occasional companion of the Avatar. He first appears as Sentri the Swashbuckler in the prison in New San Antonio in Ultima II. He later becomes the Baron and keeper of Serpent Hold, essentially the ruler of all the southern islands. In Ultima VII, he lives in Britain and is willing to train the Avatar and other companions for free after joining the party. While Sentri does not appear in Ultima IX, a magical pair of leggings belonging to him is found in Serpent's Hold."
