Côte d'Azur

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

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 in a museum on Sigma Octanus IV's surface. During the invasion, Côte d'Azur was destroyed when Spartan-117 detonated a HAVOK Nuclear Warhead underneath the city streets in order to prevent 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 all of the population was killed as the result of the nuclear explosion. during the battle.
