Tehearus Orm was a turian hitman for the Shadow Broker who specialized in sniping. A veteran of the First Contact War, Tehearus had an impressive kill count by the war's end but was decommissioned due to being drunk on the job and stabbing a salarian STG operative.
Tehearus became a Blue Sun on Omega until 2179 CE when the Shadow Broker hired him as a hit-man. Over the next six years, Tehearus assassinated multiple Alliance officers; he told his peers it was "just like old times".
In 2185 CE, he was one of five gunmen who participated in the Green Day Massacre, where he killed the brother and two informants of the late Farouk Amanesu. He was left behind by his commander, Vornel Demarian, and was arrested and sentenced to life in prison. He died five days later after hanging himself in prison.
