Krilner

Krilner is a real weakling trapped inside the prison that are the Pits of Carnage.

He was the first person the Avatar met in Ultima Underworld II and acted like a real coward. His pathetic attempt to battle the Avatar ended when he surrendered after getting a scratch. After that Krilner told the Avatar about the Pits and that he had no chance, the other warriors actually ignoring him since he was such a weakling, calling him "Krilner the Coward". He turned out to be a spring of information however, being all too eager to please the Avatar with all the information he got, essentially telling him/her everything what he/she needed to know about the Pits..

Later, when the Avatar needed to defeat Dorstag, Krilner revealed to him that defeating Zaria would really impress Dorstag into a duel, after Dorstag had denied the first challenge. After Dorstag's defeat, Krilner almost literally kissed the Avatar's feet in admiration.
