Sir Oltorain is a Mimbrate baron and an extremely minor character. He is first in the Queen of Sorcery where he and his party are engaged in a meaningless war with Baron Derigen, both claiming they had been insulted. Mandorallen challenged both Sir Oltorain and Baron Derigen to a trial by arms (joust) and unhorsed both. Sir Oltorain broke his leg after this contest. He is the older brother of Lady Ariana, a skilled Mimbrate physician.
