OXA Machine

The Odyle Xenotaph Anarchive, commonly known as the OXA Machine or OXTA, is a device created by the Psions that is capable of clairvoyance, both revealing the past and predicting the future. It was destroyed by the Cabal Empire when the Psions were conquered and enslaved. Centuries later, it was rebuilt by Freeborn Otzot.

History
At some point in the distant past, the Cabal Empire conquered the Psion race, destroying the OXA Machine as they did so. Centuries later, a brilliant Psion scientist known as Otzot recreated the machine on a Psion moon called Brand. Umun'arath dispatched a Cabal armada to bomb Brand in order to destroy the device once again, but was ordered by Emperor Calus to stand down. Rather than punish Otzot, Calus rewarded her, and the OXA Machine was integrated for the Empire's use. Calus claims to have "interpreted the mad prophecies" of either this machine or its original, one of which detailed in vague terms the long-ago rise of the Hive under Oryx, the Taken King.

During Ghaul's coup, Otzot harnessed the OXA machine to transmit plans to her co-conspirators in secret.

The Vex kept information about the OXA machine accessible through the Insight Terminus on Nessus. This information was accessed at unknown times by both Otzot and a simulated instance of Ishtar Collective scientist Maya Sundaresh. After the Red War, Kargen, the Technocrat led an offensive on the Insight Terminus, attempting to empower a prototype of the same machine.

It is later mentioned again by Tazaroc, the Sun Eater in the Season of Dawn where she describes it to have "troubled ramblings" and is a "mad thing", suggesting The Sundial was superior to the OXA in its foretelling and predictions.
