Bertroff Hissa

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.

The only person barring Trioculus's ascension to Emperor was Kadann, the Supreme Prophet of the Dark Side; gaining his dark blessing was integral to Hissa's scheme. Although Kadann initially gave Trioculus his dark blessing, he soon rescinded it, claiming the title of Emperor for himself. Trioculus was initially thought to have been killed by the Prophets, though he survived, and along with Hissa and the other Moffs began plotting as to how he would regain his throne. Trioculus, however, was killed by members of the Rebel Alliance, leaving Hissa and the Moffs to face the wrath of Kadann alone. The Supreme Prophet sentenced him to a slow and painful death, though before his execution could take place, Hissa was taken to the fourth moon of the planet Yavin, where Kadann was searching for the Lost City of the Jedi. Hissa was killed when Kadann sent him on a reconnaissance mission into a possible location of the city, which was in fact a decoy, filled with molten lava.
