Breex lived in Hillsfar, carefully disguised as a human. During the Rage of Demons, he approached Captain Haakon Erlich of the Red Plumes with an idea to become rich: kidnap non-human farmers from around the city and sell them to the Hillsfar Arena. Haakon agreed and they captured many people, included the halfling Tinfellow family and the drow Arrizz. At last, Breex and the corrupt Red Plumes tried to capture an adventuring party hired by the Harpers to find the kidnapped people. In the end, the adventuring party managed to escape from the Arena and in the fighting they killed Breex.
Breex was an intelligent and annoyingly confident individual. He was quick with a biting insult. His mind was filled with thoughts of money, even knowing that if the First Lord discovered his business he could expect a rather terrible punishment. He displayed a stupefying amount of prejudice against non-humans, but if anyone noted his orcish ancestry Breex lost all of his composure, screaming and spitting in rage.
