Tenebrous

Tenebrous was a Covenant frigate attached to the Second Fleet of Homogeneous Clarity in the 9th Age of Reclamation.

The ship was with the fleet during the Battle of Installation 05 and was under Jiralhanae command. When the Great Schism broke out, this ship assisted the Twilight Compunction and its shipmaster, Gargantum, in attacking the Sangheili-held ship Incorruptible. It was destroyed by the Incorruptible after it was hit with an energy projector.

Trivia
