Pegasi Delta

Pegasi Delta is a small world in the 51 Pegasi System. The surface of the planet was made of red rocks and sand. Orange dust permeated the sky and had a faint yellow sun, 85 Pegasi-194A around which the world orbited. It had seas that were unusually rich in Deuterium and Tritium which the Covenant used in their plasma reactors, and it was used to refuel their ships.

History

During the Human-Covenant War, the Covenant forces constructed a massive refinery on Pegasi Delta. With its close proximity to UNSC space, Pegasi Delta became a massive forward resupply and refueling line for the Covenant ships making incursions in UNSC space.

The UNSC tried many times to neutralize the refinery, including using nuclear weapons launched from slipspace. However, the plutonium linings of the weapons let off an aura of Cherenkov radiation upon reentering normal space, which therefore made their stealth coatings useless. The Covenant easily found and destroyed them. Similarly, there were too many Covenant ships near the planet's moon to send a slow, distantly-launched weapon, a regular invasion force or even Orbital Drop Shock Troopers.

In 2545, the UNSC sent in Spartan-III super-soldiers from Beta Company to destroy the refinery in Operation: TORPEDO. They successfully destroyed the refinery, crippling the Covenant supply lines, but came out with the apparent death of 296 out of the 300 Spartans of Beta Company. Because of this, Lucy-B091, one of the four surviving Spartans, was so shocked from the incident that she became mute and could not (or chose not to) speak anymore. Note that Catherine-B320 and Spartan B312 were not present in the battle.

Trivia

• Pegasi Delta is the UNSC designation for the Covenant colony. It is likely that the Covenant had their own name or designation for it, unrelated to that used by the UNSC.
