Sublime Transcendence

The Sublime Transcendence was a Covenant Supercarrier, the Flagship of the Combined Fleet of Righteous Purpose. It was commanded by Imperial Admiral Xytan 'Jar Wattinree.

In August, 2552 the ship picked up a NOVA bomb along with some mining equipment from Reach, implying that either it was present at The Battle of Reach or it had visited the planet afterward.

A few months later, during the Civil War of the Covenant, the carrier and its Fleet were at Joyous Exultation along with as many other Elite-controlled ships as could be found. They met to plan a strike against the Brutes and to decide what to do about the Flood, then later the Humans.

The ship, most of its Fleet, and the planet's moon were all destroyed when one of the Grunts on board, Kwassass, inadvertently triggered a voice cue in a databox, thereby arming the NOVA bomb: after playing a message by Admiral Whitcomb, the detonation was caused by a group of Engineers, who reinserted the databox inside the bomb itself, despite Kwassass's efforts to prevent it after realizing about the threat.

Trivia

 * There is speculation that Imperial Admiral Xytan 'Jar Wattinree may have escaped and avoided Danforth Whitcomb's instigated-NOVA bomb as Eric Nylund cues that he may yet still be alive. The Halo Encyclopedia have now confirms that Wattinree is dead - completely atomized by the blast.
