The center of the Nexus.

The Nexus is a Forerunner facility that lies directly beneath the Command Spire. Its main purpose is to direct the Reformation in conjunction with the Command Spire. The Nexus also serves as the main point of entry into the Command Spire itself, via a gravity lift.

History

On December 13, 2559, when Cortana sacrificed herself to destroy the Silent Auditorium and deny Atriox control of Zeta Halo, a large section of the Ring broke off, taking with it several key Forerunner facilities including the Nexus. Months after her death, fragments of Cortana's data lingered in and around the Nexus, manifesting themselves as ghostly echos of various memories.

On May 28, 2560, the Harbinger extracted Despondent Pyre's Encephalon and used the Forerunner routines within to construct a protocol that summoned over forty Reformation Spires, including a Command Spire, around the Halo fragment. She then traveled to the Command Spire where she attempted to send the initialization sequence needed to fully activate the Spires. However, because the protocol she'd used to summon the Spires wasn't entirely correct, the Spire network resisted her attempts to start the Reformation.

Meanwhile, John-117 entered the Nexus in order to access the Command Spire. Upon reaching the facility's central chamber, the Chief's AI companion, The Weapon, remarked on how interconnected and exquisite everything was. John, however, insisted it was a problem that needed to be dealt with. The gravity lift connecting the Nexus to the Command Spire above had been deactivated, so the Chief searched the Nexus for the three power seeds required to reactivate the lift. After fighting through multiple Aggressor Sentinels, the Chief recovered the seeds and restored power.

When the Weapon accessed the Nexus's system to reactivate the lift, the Harbinger sprung a trap and hacked the Weapon, intent on using her AI routines in combination with Despondent Pyre's to break through the network's resistance and start the Reformation. The Weapon, in turn, used her link to the Harbinger to try to steal Despondent Pyre's encephalon. Despite the Master Chief's attempt to delete the Weapon - an effort which the Weapon herself stopped - both the Harbinger and the Weapon succeeded in their respective goals. This caused friction between the Chief and the Weapon, with the Chief being angry that the Weapon had stopped him from deleting her and had thus allowed the Reformation to begin, while the Weapon - who believed the Harbinger would have found a way to start the Reformation regardless - was angry that the Chief had tried to delete her in the first place rather than trust her.

With the Nexus's gravity lift back online, the Chief rode it into the Command Spire itself.
