Breath of Annihilation

Breath of Annihilation, informally referred to as the Annihilation, is a in service with Jul 'Mdama's reformed Covenant faction. Along with 'Mdama's Song of Retribution, Breath of Annihilation is one of the two assault carriers that makes up the faction's primary contingent fleet.

Battle of Aktis IV
During the Battle of Aktis IV, Breath of Annihilation along with another CAS-class assault carrier and a were hidden underneath an ocean of an unknown, foam-like substance on Aktis IV which prevented 's sensors from detecting them. The ships were to be used by 'Mdama in his plan to ambush the UNSC forces in order to take possession of their half of the Janus Key. After the Pelican carrying the key was shot down by Sali 'Nyon's artillery, however, the Breath of Annihilation's shipmaster gave the order to assault the UNSC forces despite receiving no attack order from 'Mdama. Breath of Annihilation and the other Covenant ships then emerged from the ocean and launched their attack against the human forces on the nearby island.

The carrier battled UNSC Infinity and her sub-vessels over the planet, alongside Song of Retribution and and smaller Covenant cruisers, preventing Infinity from moving or supporting its deployed ground forces. After Jul's forces managed to procure both halves of the Janus Key, 'Mdama and his forces fled the system.

The Absolute Record
Using the Janus Key, 'Mdama's faction worked to pinpoint the location of the Absolute Record, a repository of Forerunner knowledge. On September 15, 2558, while within the Urs system, Doctor Catherine Halsey believed she discovered the Absolute Record's location while analyzing the Janus Key. Meanwhile, the UNSC's Office of Naval Intelligence put together a team composed of Spartans Sarah Palmer, Gabriel Thorne, Holly Tanaka, Doctor Henry Glassman, and Ayit 'Sevi—a mercenary within Jul's ranks working for ONI. Using 'Sevi's false affiliation with Jul's forces, the team took a Phantom and stalled away aboard Breath of Annihilation, with the intention of revealing the location of the Absolute Record to the UNSC. When Breath of Annihilation and the rest of the fleet departed for the Absolute Record's apparent location, they discovered an apparently artificial gas giant with a slipspace portal leading to their true destination. However, slipspace ruptures suddenly destroyed two cruisers within the fleet and heavily damaged Annihilation.
