Noctus

Noctus is the capital city of Andesia, a human colony governed by the Unified Earth Government. Noctus is home to several local medical research and ultra-tech industries.

History
Noctus was one of the first cities established after Andesia's colonization by biotech associations. In 2523, a rebellion broke out on Andesia in response to the Unified Earth Government'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. The insurgency eventually reached the heavily defended facilities of AMG Transport Dynamics located in Noctus.

After nearly a decade of fighting, the conflict was finally ended when the Insurrectionists on the planet agreed to temporarily establish peace with the UEG and UNSC after they realized that the Covenant was a greater threat. After the Human-Covenant War, the UNSC trained SPARTAN-IVs in a War Games simulation of Noctus to prepare them for a possible resurgence of rebellion in the city as tensions remained high. The UNSC trained these Spartans to secure strategic facilities in the city, similarly to what the UNSC did during the rebellion decades earlier.

Trivia
The Halo 5: Guardians multiplayer maps Empire, Eden, and Plaza take place in Noctus.
