Teregus is a gargoyle responsible for the Shrines of the Principles on Terfin. Lord Draxinusom directed the Avatar to Teregus in Ultima VII after being told of the murder of Inamo, as Teregus had raised Inamo from an egg. After being told of Inamo's death, Teregus was in shock and needed time to grieve for his child. When the Avatar found out that Sarpling and Runeb had planned to destroy the shrines, he asked the hero to confront Runeb, which in the end resulted in Runeb's death.
