[quote]So before anything else is said, you need a basic understating of the Vex goal. The Vex are searching for what they call "an emperor to all outcomes." This means they want to have something in place so that no matter what happens they have some kind of response that ultimately leads to a Vex victory. The Black Garden and the Vault of Glass are two such projects built to fulfill two separate victory conditions. Atheon was the Vex Axis Mind in charge of the Vault. The Vault is most likely the culmination of Vex efforts to understand and replicate a Hive Throne World based on what Quria, Blade Transform learned during his war with Oryx before being defeated. The Vex want to use the vault to establish themselves as a fundamental rule of existence. The Templar's Ritual of Negation and Oracles work because the Vex have established a level of control over the very nature of reality within the Vault. The Oracles are able to tag enemies and then the Templar uses the ritual to delete what the Oracles tag from existence. Put another way, the Oracles decide how the Vex want to change and shape reality and the Templar makes that reality so. The Gorgons are a similar but slightly different. Gorgons can both tag and delete, but they must physically see what they want to change while the Oracle-Templar combo do not. The Relic/Aegis was created by Kabr, the Titan who led the original failed raid of the vault. He built it by merging his dying light and what remained of his ghost with the body of a Gorgon he destroyed. This allows future Guardians to channel and use light to shape reality within the Vault with their light and the Vex can't destroy it because its made of a Gorgon. This is why the Relic can destroy the Templar's shield for example. The final area is the Glass Throne and is the seat of Atheon, Time's Conflux. All time bends around itself and meets in this place. Precursor, Descendent, and modern Vex all exist because the future, past, and present all exist here. The timegates in the room don't lead to "Mars" and "Venus" as most call it, but to past and future versions of the Vault. Two relics exist here for a short while because you pull one from a past version of the Vault and one from a future version of the Vault. Atheon teleports you to separate you so that you can be killed individually and because, as the blinding effects shows, guardians don't seem to do very well when pulled out of our time of origin. We are saved again by the Aegis because Kabr made it so it is a fundamental rule within the Vault. It exists in the past and future and we use it to pull ourselves back into the present. When we do so after being teleported it activates the "Time's Vengeance" effect. This cause all timelines to temporarily and partially merge. Your weapon does so much extra damage because for a brief time it isn't just your 6 man fireteam doing damage, but every guardian that ever has and ever will reach Atheon from every timeline coming together. I know I didn't hit all of your questions, but I hope this helps![/quote]
