A global war on the Elite homeworld of Sanghelios erupted in late 2558.[1] Fighting would involve the Swords of Sanghelios, Jul 'Mdama's Covenant, minor forces of the United Nations Space Command (UNSC), and finally the newly formed Created.[2]



Jul 'Mdama's Covenant would gain control of Sunaion and began to plan for a strike on Vadam. The Swords of Sanghelios would be made aware of this and would establish a forward operating base in the ruins of Nuusra. They would hope to strike the Covenant at Sunaion.[3]

Leading into the conflict, Sanghelios was in a tense state.[4]


Sometime after the death of Jul 'Mdama, his Covenant attacked the planet. As their forces attacked, other assets on the planet rose up. Sanghelios burst into a worldwide conflict. Despite, the battles on the planet previous to this point, this was the first time that fighting on Sanghelios was characterized as a global war.[1]

Fighting at Nuusra[edit]

"With Arbiter's victories and the death of Jul 'Mdama, the Covenant grow desperate. They have began an assault on 'Vadam lands, targeting Arbiter specifically."

On October 27, 2558, the Covenant made a last-ditch attempt to kill the Arbiter[1][5] at Nuusra. Partway through the battle, the Fireteam Osiris would assist Swords forces in repelling the Covenant and extracting the Arbiter Thel 'Vadam.[5]

After discussions took place between human forces and the Swords,[6] Fireteam Osiris would move to a Forerunner installation to retrieve a Constructor.[7]

With it, the humans modified it to activate the Guardian beneath the sea city of Sunaion. Sunaion was also at this point, the Covenant's last stronghold. Together, the humans and the Swords of Sanghelios left Nuusra to attack.[8]

Last stand[edit]

"The Covenant soldiers will hear the Guardian wake from its slumber, they will look up over the bodies of their brothers, through the smoke of their burning city, they will look to the horizon as their holy idol rises from the sea and forsakes them. And that is when the Covenant dies."
— Thel 'Vadam to a few of his officers.[6]

The Swords of Sanghelios moved into Sunaion deploying Thel himself and Fireteam Osiris. They would split up with Osiris moving to take out anti-aircraft weapons. At least one ship in the air above the battle fell into the Csurdon Sea below. Osiris eventually went into the under city fighting Covenant forces there. The Guardian buried below began to rise, and with it Created forces joined the fray.[9]
