Bliss

Bliss was a human colony world governed by the Unified Earth Government, with its capital at Manikata. Bliss was orbited by one natural satellite, Aires. The planet and its system was protected by the Bliss Defense Fleet.

History
On February 13, 2526, a fleet of 45 Covenant vessels, including five assault carriers, 23 battlecruisers, and 17 destroyers, entered the planet's system. Three UNSC ships, including the heavy cruisers and, as well as the frigate , engaged the Covenant fleet. The battle lasted about three minutes and resulted in the glassing of the colony. The destruction of Bliss later led to dissident leaders among the Outer Colonies agreeing to peace with the UNSC.

Professor Ellen Anders of Rishard University on Arcadia noted that Bliss, Cote d'Azure, and Onyx had "large-scale engineered features", suggesting the presence of Forerunner structures on the planet.

Trivia
Intersystem News reported that an estimated 500 million people were feared dead after the glassing of Bliss. This contradicts the data pads in Halo: Reach, which put all human casualties in the Human-Covenant War by 2530 at 62,154,022.
