Assault on the Mortal Reverie

The Assault on the Mortal Reverie is a massive assault by Banished forces on the UNSC base located in the wreckage of the during the Battle for Zeta Halo.

Background
On December 12, 2559, the traveled to Installation 07 in order to deploy the Weapon and stop Cortana. However, the Infinity and her fleet were attacked by Banished forces, resulting in the apparent destruction of the supercarrier, forcing the survivors to evacuate to Zeta Halo's surface.

On December 15, Spartan Vedrana Makovich discovered the wreckage of the and determined it to be a viable location for the UNSC's base of operations. On January 23, 2560, Spartan Hudson Griffin led Spartans Panago, Malik, and Sarkar on an assassination mission on Escharum. Griffin left Bertold Vettel in charge of the UNSC forces at Reverie. However, Escharum anticipated Griffin's actions. His forces ambushed the Spartan team, killing the other three and leaving Griffin badly wounded. Escharum taunted Griffin, letting him know that he'd sent most of his forces to assault the Reverie. Griffin managed to send an encrypted message to warn the Reverie before Escharum captured and handed him over to Chak 'Lok for torture. Under the combined leadership of Vettel and the counsel of Makovich, the UNSC forces at the Reverie braced for the Banished's attack.

On January 31, Jiralhanae Chieftain Tremonius and Captain Arthoc gathered a massive Banished assault force at Riven Gate. Spartan Stone and Boulder Squad conducted a recon sweep at Riven Gate. Stone reported her findings to Mortal Reverie, and warned the Reverie that the Banished would arrive by nightfall. The UNSC survivors at the Mortal Reverie prepared for the Banished assault. Spartans Makovich and Vettel discussed the UNSC's inability to win the upcoming battle and their dwindling options for the future.

Battle
From January 31 to February 2, the Banished forces led by Jiralhanae Chieftain Tremonius assaulted the wreckage of the. Infantry and armor poured into the valley by the hundreds, overwhelming the UNSC defense and killing most of the survivors. Spartan Bertold Vettel was reluctant to abandon the Reverie, knowing that if they lost the Reverie, they lost everything that they had left. However, completely overwhelmed by the sheer number of Banished forces, Spartans Nina Kovan and Vedrana Makovich convinced Vettel that they had no other choice and Vettel ordered the surviving UNSC personnel to abandon the Reverie, leaving it to the Banished.

Aftermath
Following the battle, the crash site surrounding the ship was converted into a Banished outpost. As a reward for Tremonius' victory, Escharum had the outpost named after Tremonius, who would be promoted to the rank of Warlord. The loss of the Reverie and the last of the Forward Operating Bases on the fragmented section of the ring on March 3 saw the end of all major UNSC resistance on the fragmented section of Zeta Halo until May.

On May 28, John-117 was rescued by Echo 216 from the debris field around the installation. While retrieving the Weapon from the ring's foundations, the Master Chief killed Tremonius and retook Outpost Tremonius for the UNSC for the first time since the fall of the Mortal Reverie.
