The Razing of Oth Sonin was a Created attack on the Oth Sonin system, resulting in the destruction of the Jiralhanae homeworld Doisac and the devastation of its moons.

Background

Banished dominance

Atriox's Banished had united the Jiralhanae clans across Doisac and its moons, though there were clans, such as those on Warial, who refused to join the Banished, as they considered the Banished to be too similar to the Covenant and were wary of any alliance that resembled the former empire.

Created uprising

Cortana and her Created came to power in October 2558. They subdued the galaxy with their Forerunner constructs known as Guardians, seeking to enforce a martial peace.

This violence made the Oth Sonin system a hotspot for the Created to subdue.

The Banished and its allied clans staged a defensive against the Created in their home system. They fought hard against Cortana's forces.

Atriox himself having previously been on the Ark, returned to the galaxy following the events of Operation: WOLFE and was preparing a force to head to Installation 07 to find the Xalanyn.
