Reach

''Reach describes the planet. For the upcoming game, see Halo: Reach.''

Reach was a Human world in the Epsilon Eridani System, located within the Inner Colonies. This planet was one of the most important headquarters for the United Nations Space Command and the main supplier of military and civilian spacecraft. High Command, Fleet Command and the Marine Corps maintained headquarters on Reach, as well as many primary Naval Intelligence bases, which included the highly classified CASTLE Base. Reach's purpose was not solely military however; the surface of the planet also featured farmland and civilian towns and districts.

After the Battle of Reach, the planet was mostly glassed. When UNSC forces finally abandoned the planet, a small Covenant occupation fleet remained in the system.

Introduction
Reach is the 4th largest planet in the Epsilon Eridani system, and second closest to the star ε Eridani. Reach is stable for planet of its age, approximately one billion years. Reach is the location of the UNSC's largest and most active shipyard. It is also where the UNSC's most elite troops, the Orbital Drop Shock Troopers, are trained. Reach is also the largest non-automated exporter of titanium. ε Eridani's superior interstellar jump point has been the most active S-F space transfer zone (arrivals and departures) for over thirty years, with ε Eridani's inferior IJP and Sol's superior IJP regularly trading second and third place spots.

UNSC Powerhouse
First planetary confirmations of Reach were in early 21st century. Originally colonized for its rich titanium deposits, Reach had mines throughout it running thousands of meters deep. ONI's secret CASTLE base was located in one of these mines underneath Menachite Mountain. ONI commandeered the mine after it breached a secret area beneath Reach's surface containing a Forerunner artifact that was highly desired by the Covenant. The fact that this artifact was so valuable to them is perhaps the main reason anyone survived the aftermath of the Battle of Reach at all, as the Covenant were afraid of destroying it. This facility was also the birthplace of the legendary SPARTAN-II Program.

Despite its position as the UNSC's largest naval base, strategic headquarters, and second-largest population center, the Epsilon Eridani system was wracked by Insurrectionist activity throughout the early 26th Century. Reach's sister planet, Tribute, was one of the fronts for the UNSC's anti-terrorist campaign, Operation: TREBUCHET. In 2525, mere months prior to the outbreak of the Human-Covenant War, Reach was the site of a major terrorist bombing against the luxury liner National Holiday. Two taxi-shuttles filled with explosives were crashed into the liner, resulting in the liner to loose control and plummet into the atmosphere, incinerating everyone on board.

The Fall of Reach
Reach's darkest hour was near the close of the Human-Covenant War in 2552. The Covenant discovered the location of Reach from a Forerunner artifact recovered during the Battle of Sigma Octanus IV. That artifact disclosed its locality, as Reach was the location of yet another artifact. Coincidentally the Human presence on Reach was revealed when the destroyer Iroquois returned to Reach ensuing the battle, unaware that a Covenant spy drone was attached to her hull near the engines. As such the Covenant were aware of the defender's strength prior to the assault.

The UNSC had formulated a plan to end the war. A platoon of SPARTAN-IIs would hijack a Covenant ship, head to their home planet, kidnap the Covenant leadership, and use them to broker a truce with the Covenant. The Spartans were aboard the UNSC Pillar of Autumn with Captain Keyes and his crew. They were just about to leave for their mission when a signal ordered their immediate recall to Reach to defend the planet against a massive Covenant attack. Master Chief Petty Officer John-117 ordered the majority of the SPARTANs to the planet's surface to protect the generators for the Orbital Defense Platforms while he and two other Spartans boarded Reach Station Gamma to secure an unprotected NAV database aboard the ONI corvette Circumference.

The battle was a disaster for the numerically-inferior UNSC fleet, despite the Super MAC Guns, resulting in the planet's destruction by means of plasma bombardment. CASTLE base was destroyed after the planet's fall and the Covenant began searching for a Forerunner crystal. UNSC forces finally abandoned the planet during the Raid of Reach, a few weeks later.

Defenses
Orbiting around Reach were twenty Orbital Defense Platforms (ODP), equipped with heavy MAC Guns also known as "big sticks," some of which were in place as early as 2527. In addition, there were also about 100 to 150 warships stationed in the Epsilon Eridani System at any time. The ODPs were destroyed during the Invasion of Reach, or were disabled by ground troops by destroying their power source. Despite their huge numbers, the fleet of warships was destroyed by an even larger Covenant fleet.
