Arcadia is a United Nations Space Command colony located in the Procyon System.

The Forerunners
The Forerunners apparently had a presence on Arcadia before the Forerunner-Flood War, leaving behind a building complex that later became a site of conflict in 2531.

Human Colonization
Upon Human discovery of Arcadia, the had no need for terraforming, already inhabited by dense jungles and large oceans. Arcadia was rich in natural resources, and almost no change was made to it's geographical features. The UNSC established the largest landmasses into six continents; Eire, Pacifica, Mu, Caledonia, Lemuria and Avalon. Pirth City in Mu, became the largest city on the planet, and soon the capital city.

Arcadia became a center for agriculture, research and recreational activities. It was also home to the Deep Space Research Array. However, despite all of this, Arcadia's population and structures were all very clustered, leaving huge areas of the planet unexplored.

Human-Covenant War
By 2531, it had a population of approximately three million. However, it became a site of conflict in 2531, caught up in the Human-Covenant War, after a Forerunner stellar map on Harvest pointed the Arbiter Ripa 'Moramee towards the colony. Eventually, the Covenant were pushed off by the efforts of the crew of the, allowing much of its civilian populace to be evacuated. The capital city of Pirth would soon become overtaken by nature. Meanwhile, the remaining colonists formed the farming community of Abaskun on the continent of Mu. It would remain a mostly lawless region, but continued to supply the UNSC with food. The Covenant would return to Arcadia later in the war, destroying it.
