Sigma Octanus IV

Sigma Octanus IV, located in the Sigma Octanus star system, is an out-of-the-way colony planet with one moon and a population of nearly seventeen million citizens before The Battle of Sigma Octanus IV. It features a warm, humid atmosphere that is perfect for growing warm weather crops, like rice. The planet has many rice fields. Much of the planet is a dense jungle and it appears that a meteor containing Forerunner artefacts crashed on the planet before Humanity's arrival.

History
On July of 2552, the Battle of Sigma Octanus IV began with the invasion of the crusading alien faction, the Covenant. One of the planet's major population centres, Côte d'Azur, was attacked by Covenant ground forces and the Spartans were deployed to find out why the Covenant were so interested in the city. The museum of the city held a Forerunner artifact that the Covenant wanted and the Spartans were able to retrieve this artefact, more specifically a rock sample with rubies in it, and level Côte d´ Azur and the Covenant presence within with a HAVOK Nuclear Warhead. Later on, it is revealed that the Forerunner artefact contained directions to Installation 04. This is the first place Engineers and Hunters were seen in combat.

It is the only known human-controlled world, with the exception of Earth, that has survived a Covenant assault. The assault on Sigma Octanus was a distraction to remove the Forerunner artefact, and is most likely why Sigma Octanus IV survived.
