The Ravaged Tusks are a Jiralhanae-led clan under the leadership of Chieftain Ballas. While the clan serves as a legion within the Banished, Ballas holds the rank of Legionmaster. The clan is known to be smugglers and slavers.
By July 2559, the Ravaged Tusks had been absorbed into the Banished. When War Chief Escharum received a transmission from Atriox that ordered him to find a Forerunner portal rumored to be hidden on Reach so that he could leave the Ark and return to the galaxy, the Ravaged Tusks were sent to the human colony, alongside the Keepers of the One Freedom and the Legion of the Corpse-Moon, to search for this "Portal under the Mountain."
After landing on Reach, the clans were each assigned a third of the world to search, the supercontinent of Eposz being split into thirds as well. Ballas and the Ravaged Tusks had been assigned the southwest third. However, the three clans had little luck in finding this near-mythical portal. Ballas and Chieftain Deukalion, who led the Legion of the Corpse-Moon, started to squabble with over the resources found within the human rehabilitation settlements spread across their search areas. Dokab Castor, who led the Keepers, was able to reason with Ballas and Deukalion convincing them to continue their search for the portal. Recently, a Spartan team had arrived on Reach as part of a mission to recover key assets from the ruins of CASTLE Base. Castor did not know of their true objective, but he felt sure that they were searching for the portal.
As part of Castor's plan to follow the Spartan team, forces from the Ravaged Tusks and Legion of the Corpse-Moon would continue to harass them. Ballas' forces also participated in the failed defense and recapture of New Mohács, a settlement ran by the Viery Militia. Luckily for the Banished, the Spartans did lead the three clans to the portal, as CASTLE Base happened to sit atop the Forerunner complex.
The Ravaged Tusks make use of various Banished vehicles and weaponry, such as Marauders, Wraiths, Banshees, Phantoms, Seraphs, Type-2 gravity hammers, pulse carbines, and Type-25 Spikers. Species such as Unggoy and Kig-Yar serve within their ranks under the Jiralhanae.
