Rodrick

Rodrick is a former member of the Knights of the Crux Ansata who'd turned traitor, calling himself the "Chaos Knight".

When the Avatar asked around in the fourth level of the Abyss in Ultima Underworld I, the hero learned fast that the knights and the Trolls both feared Rodrick, who terrorized the whole level. However, for the finaq quest to become a knight, the Avatar had to confront Rodrick, since he had the only key to the needed item.

Rodrick gave a small warning, then attacked. It was a tough battle, but finally the fiend was slain. Dorna Ironfist was so impressed, that he gave the Avatar the Standard of Honor as a reward.

Trivia

 * In the Ultima Underworld I Clue Book, Tyball is real proud to admit that Rodrick' evilness had been his work, corrupting him over time into the monster seen in the game.
