Andesia

Andesia is a human colony world, governed by the Unified Earth Government. The planet's capital is Noctus. Andesia is controlled by a mega-corporate council that is largely resented by the planet's residents.

History
In 2523, in response to the UEG's tightening grip on the human colonies and the excessive control taken by the mega-corporate council that served as the de facto planetary government, a rebellion broke out on the planet. The insurgency even reached the heavily defended facilities of AMG Transport Dynamics located in the capital city of Noctus. Members of the Insurrection established a stronghold on the planet. In response, the UNSC Defense Force sent troops, including the 10th Shock Troops Battalion, to Andesia to eliminate the rebel presence.

During a firefight with Insurrectionists lasting for approximately seven hours, Ridge, a member of Cadmon Lasky's ODST squad was killed. Afterwards, Cadmon estimated that he must have killed a dozen of the Insurrectionists. Sometime later, Cadmon and the rest of his squad was killed in action on the planet. The fighting continued on the planet for nearly a decade, until the realization of the true threat of the Covenant caused Andesia's citizens to realign themselves with the UNSC and UEG to survive. The colony ultimately survived the Human-Covenant War, although tensions between the planet's citizens and the UNSC remained high. SPARTAN-IVs are trained in a War Games simulation based of of Noctus to prepare them for the eventual rise of insurgents on the planet, and to have them ready to secure strategic facilities when said insurrection occurs.

Trivia
Andesia is a genus of moths of the Noctuidae family.
