"Arcadia colony, to be precise. Population a little under three million, largely unexplored, but apparently quite the vacation resort."
— Serina[4]

Arcadia is the fourth planet in the Procyon system, orbited by two natural satellites—Gihon and Pishon. Colonized in 2429,[1] Arcadia was a human Outer Colony of the Unified Earth Government, home to a population of nearly three million.[4] A thriving colony,[1] Arcadia was a popular tourist destination, famed for its lush jungles and forests.[5]

On February 9, 2531, Arcadia was attacked by the Covenant, leading to a brief, yet brutal, battle between the United Nations Space Command and the Covenant.[5] Although Admiral Preston Cole successfully fought off the Covenant forces, Arcadia's major population centers were destroyed and the Arcadians abandoned their home. However, over the following years, many Arcadians slowly returned to their homeworld and began rebuilding their colony.[6]

On September 9, 2549, the Covenant returned to Arcadia and finally glassed the planet, eradicating nearly its entire population.[5]

Astronomical features[edit]

Arcadia is a tropical planet orbiting the star Procyon,[7][2]. Slightly larger in size than Earth, the planet has a diameter of 13,019 kilometers (8,090 miles). Arcadia has an approximated gravity of 1.02 G, with an average surface temperature varying from 3 °C to 37 °C (37 °F to 98.6 °F).[1] Regarded as atmospherically tropical,[7] Arcadia's oxygen-nitrogen atmosphere had an atmospheric pressure of 1.3 atm.[1]

Environmental features[edit]

Arcadia's landmasses were divided into six designated continents: Eire, Pacifica, Mu, Caledonia, Lemuria, and Avalon. Even before humans colonized the planet, Arcadia already maintained environments and natural resources suitable for human habitation, requiring no aggressive terraforming measures.[5] Arcadia's surface was largely unexplored beyond the colony's limited settlements and tourist zones, preventing the discovery of the Forerunner ruins on the planet for a long period of time.[7]
