Battle of Creshen

While initially not willing to partake in the Great Schism, many minds would be changed after the local San'Shyuum Exarch and his Jiralhanae Chieftain began to attack Creshen and it's local outposts. Their initial assault would lead to the destruction of several colonies on Creshen's moons and decimate several regions to near uninhabitability which the Jiralhanae hoped would weaken the defenders. In conjuncture with local Sangheili-allied forces, and the newly arrived Fleet of Eternal Conviction led by Garr 'Alakavai and Imperial Admiral Khito Tar 'Nucam, the defenders count-attacked against Covenant forces, hardened by the devastation caused by them. High Councilor 'Alakavai would convince his fellow Cresheans and nearby worlds to official join his own remnant faction, the Wartorn.

The last of the Covenant forces would be forced into a ground battle. Pushed to the very edge, the Jiralhanae encircled and defended their Exarch as the Sangheili warriors slaughtered them ruthlessly. As the last of the brutes were killed, High Councilor 'Alakavai slew the helpless San'Shyuum himself. This site would later serve as the headquarters of the Wartorn.

Aftermath
With the defeat of Covenant invaders, many on Creshen would become thankful towards the Wartorn, a group that comprised of many native Creshaens even before the intervention. After joining, Creshen became the primary world within the Wartorn and began to build their ships after uploading their design patterns.
