Political and military information





Gargantum was a Jiralhanae Chieftain and Shipmaster of the Covenant frigate Twilight Compunction.[1] The suffix "-um", on the end of Gargantum's name, suggests he is likely of the Rh'tol skein.[2]


Installation 05[edit]

He was aboard his ship during the Battle of Installation 05 and when the Great Schism broke out, he took control of several other Jiralhanae-held ships in the Second Fleet of Homogeneous Clarity and brought them to attack the Sangheili ships.[1] His ship, along with the Tenebrous, tried to attack the Sangheili ship, Incorruptible, but the attack was stopped when the Tenebrous was destroyed by the Incorruptible and the Twilight Compunction was attacked and damaged by the Sangheili carrier Lawgiver.[3]

The chase[edit]

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 a team of Spartans.[4]

He sent one frigate to attack it,[5] 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.[6]
