Côte d'Azur

Côte d'Azur was a coastal city that was the main population center of Sigma Octanus IV, a UNSC colony world in FLEETCOM Sector Three.

Côte d'Azur grew rice paddies outside of the city. The main sections inside of Côte d'Azur were: the wharf areas, the residential section, the downtown, and the docks. Côte d'Azur had a sewer system under the city made. The sewer systems have steel pipes running along the top of the plastic conduits. The sewer systems have a two meter diameter pipe, with a steel grate, on the beach side near the edge of the city. And the inhabitants used sodium vapor lamps which washed everything above an eerie glow.

In the year 2552, the Covenant launched a small attack against the Sigma Octanus system in hopes to retrieve a Forerunner artifact that was on display at the Côte d'Azur Museum of Natural History on Sigma Octanus IV's surface. The Covenant were in the process of securing the artifact and relaying messages to the ships above when Blue Team entered the city. Blue Team managed to retrieve the artifact and escape back to their PelicanDropship. Upon entering the Pelican and exiting the atmosphere, John-117 detonated a HAVOK Nuclear Warhead underneath the city streets which destroyed the city and prevented the Covenant from finding anything else of value. The planet still remains under Human control. The population of Côte D'Azur was estimated to be 300,000, however 20 civilians hid in a cargo ship that were eventually evacuated by the Spartans during the battle.
