Dorna Ironfist

Dorna Ironfist is the leader of the Knights of the Crux Ansata on the forth 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 of him yet.

The Avatar asked to join the order, and Dorna Ironfist gave four quests to the Avatar:
 * First was a test of smarts and humility in form of several questions.
 * Second was a test of Valor. The Avatar had to drink from a chalice that could hold pison (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.
 * Fourth and last, 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.
