Bertroff Hissa was a near-Human Imperial Grand Moff who was the leading figure in an attempt to overthrow Ysanne Isard as the head of the Galactic Empire in 5 ABY. Born to a Human father and a Sephi mother, Hissa operated out of the Kessel system during the Galactic Civil War, becoming allies with Trioculus, a three-eyed slavelord. After Emperor Palpatine's death at the Battle of Endor in 4 ABY, Hissa founded the Central Committee of Grand Moffs, who installed Trioculus as their figurehead, claiming he was the son of Emperor Palpatine.
