The ship was present during the Battle of Installation 05 and when the Great Schism broke out, Gargantum ordered his ship to attack the Elite held ships. The Twilight Compunction, along with the Tenebrous, tried to attack the Elite held Incorruptible, but the attack was stopped when the Tenebrous was destroyed by the Incorruptible and the Twilight Compunction was attacked and damaged by the Carrier Lawgiver.
Gargantum's ship, along with the Revenant and another Frigate, followed the Incorruptible as it tried to escape. When the ship Bloodied Spirit dropped out of Slipspace nearby, Gargantum hailed it and discovered it was controlled by Spartan-IIs. He sent one Frigate to attack it, but while his forces were divided, the Revenant was destroyed by the Incorruptible. Gargantum then took his two remaining ships to pursue the Bloodied Spirit, closely followed by the Incorruptible.
