Dorna Ironfist

Dorna Ironfist is the leader of the Knights of the Crux Ansata on the fourth level of the Abyss. He'd gotten locked in when the colony had been turned into a prison, but remained virtuous.

The Avatar met him in Ultima Underworld I. Dorna told the hero the history of their order, before adding that they now had a grave enemy in the chaos knight Rodrick. He added he'd sent Biden to deal with Rodrick, but hadn't heard from him yet.

The Avatar asked to join the order, and Dorna Ironfist gave four quests to the Avatar:
 * First, was a test of intelligence and Humility in the form of several questions.
 * Second, was a test of Valor. The Avatar had to drink from a chalice that could hold poison (it didn't) without hesitation. Afterwards, admitting to have been scared impressed Dorna because of its Honesty.
 * Third, was the quest to get back the Writ of Lorne from the Trolls. The Avatar bribed Rawstag with a red gem to reach the writ.
 * Finally, the Avatar had to recover the golden plate from the graves in the north-west. However, that meant the hero had to battle Rodrick and defeat the foe, in order to get access.

After all tasks were done, Dorna declared the Avatar a knight and enabled access to the armoury. Additionally, for slaying Rodrick, the Avatar received the Standard of Honor from Ironfist. Later, Ironfist was rescued by Garamon, when the volcano erupted.
