In 2974 BBY, Dreypa and his rebels retreated to Sessal Spire after sustaining heavy losses at the hands of the Tribe's forces during the Battle of the Marisota Floodplain. There, Dreypa awoke his hibernating Leviathan monsters and unleashed them on both his former allies and pursuers. The Leviathans also devoured an entire army consisting of members of the Doomed—the descendants of former Jedi and Dark Jedi who had landed on Kesh following the Hundred-Year Darkness and had since made peace with each other, intending to find a balance in the Force. Following the Siege of Tahv, the Sith Parlan Spinner flew an ancient Jedi starship, the Last Hope, to Sessal Spire. There, he pretended to surrender the starship to Dreypa, who was intent on returning to the wider galaxy. However, Spinner had set the starship on an autopilot course towards Sessal Spire. The Last Hope crashed into Sessal Spire's crater and was engulfed, killing Baron Dreypa in the process.
