The pack which crewed the Valorous Salvation was in fact the product of two separate packs which had recently been merged by the Covenant leadership. The two clans were ancient enemies that had fought even before the massive civil war that had knocked the Jiralhanae back to a pre-industrial state. Naturally led to tensions in the two factions with the pack. One clan, led by brothers Ceretus and Maladus, felt themselves to be the more intelligent faction of the pack, and their devout religious beliefs were more in line with those of the Prophets. The other faction, led by the pack's Chieftain Parabum, believed only in muscle and tradition, and used relics in more opportunistic and disrespectful ways.
During the Fall of Reach, Parabum exhibited cowardice when he ordered the ship to retreat from the massive attack and instead landed on the nearby Beta Gabriel. When they first arrived on the planet, they hunted the humans they found there and feasted like never before. Ceretus and Maladus didn't even bother using their Spikers, as they had more fun killing them with their bare hands. As the number of humans dwindled, they ate the Unggoy who had been aboard the ship, and Parabum instituted limits on hunting and eating the humans.
Parabum wisely kept the Valorous Salvation under constant guard in case the other faction tried to take the ship and leave the planet. His suspicions proved justified when shortly afterward Maladus snapped and challenged Parabum over his cowardice and abandonment of their duties to the Covenant. However, Parabum was stronger and mercilessly pummeled him into submission before tearing his throat out with his teeth. This only served to further enrage Ceretus.
Eventually, Ceretus orchestrated a confrontation with Parabum which soon erupted into a brawl. Pandemonium reigned and many of the Brutes were killed as they turned on each other. UNSC reinforcements landed on Beta Gabriel soon after and eliminated all of the Brute survivors. It is unknown what became of the ship after that. It may have been destroyed in the chaos or the UNSC assault, or else captured by the UNSC.
