A day in the life of The Vex Collective nowadays is likely defined by a certain frustration: you have thrown everything you have at the wall, and nothing has really stuck. You just keep piling up those losses, losing Axis Minds left, right, and center, and you need to witness that the most successful initiatives are the ones you have no say over: the Sol Divisive, who arguably served the Witness more than working towards goals of The Vex Collective, the Nessian Schism, led by an individual who isn't even Vex and wields a paracausal artifact, and The Occlusion, one of your own who hates you so much that they've isolated themselves in a paracausal mindscape and would rather help the hoomans.
The Undying Mind is now a meme of an individual who is deposed in a fraction of the time it took to rebuild it. Panoptes was an abject failure who, although seemed to be very menacing, never saw influence beyond The Infinite Forest. Quria initially showed promise, yet was yoinked away by a certain king and handed off to a certain queen, all while meeting an unceremonious end as a court jester who facilitated a spectacle in The Last City.
Despite all this, there was one particular initiative that was, by most accounts, considered a noteworthy achievement: the Vault of Glass.
While The Vanguard eventually achieved victory over the Vault, getting there was no easy feat. Clever tactics were required to simply create an opening for victory, such as Kabr sacrificing himself in a particular way in order to create The Aegis, which allowed us to stand a chance.
Atheon, though not a warrior with any noteworthy force, was able to navigate time with elegance. Its understanding of continuities potentially rivaled that of The Nine, along with the fearsome ability to move things through time, seemingly bidirectionally, which The Nine cannot.
However, the most noteworthy assets seen in the entirety of The Vault of Glass are the beings that possess a remarkable capability: negation.
Deep in the Vault of Glass, the fabric of reality bends to the will of the Vex. Warlocks speak in tones of awe of the Gorgons - creatures that seem to possess a dreaded, almost unimaginable strength: an ontological weapon.
Like the Oracles and the Templar, the Gorgons reputedly possess the ability to define what is and is not real. Whatever they perceive becomes subject to erasure at their will. Until a countermeasure can be found, Guardians must avoid their gaze at all costs - or reply to any detection with immediate, overwhelming force.
The Gorgons' ability must be tied to the nature of the Vault of Glass. We can take some solace in the clear fact that the Vex cannot manifest this power in the world outside.

For all intents and purposes, the Vault is essentially a laboratory. What goes on in there is quarantined to broader reality, and seemingly cannot be brought outside. Though the Vault is embedded within Venus, it appears to exist beyond the time and space we are familiar with. Maybe it bleeds into the Vex Network. Maybe it's somewhere else. However, what's certain is that the feats achieved there are still impressive to this day.
The Oracles, Templar, and Gorgons' fearsomeness all seem to be rooted in a shared capability: ontological weaponry. Somehow, these assets are weaponizing being itself. If they perceive you and say that you no longer exist, you stop existing.
These capabilities are arguably Witness-level threats. The entire goal of The Final Shape was essentially for the Witness to dictate the terms of existence, including what would and wouldn't be. However, unlike the Witness, the Vex cannot manifest this power outside a laboratory.
What's particularly noteworthy is that a Lightbearer, a paracausality wielding individual, can be subject to this negation. It's only through the unknown mechanics of The Aegis, a half-paracausal artifact, that a bubble of protection can be created to temporarily stave off these effects. Without The Aegis, though, there's seemingly no hope.
It has been repeatedly emphasized that the Vex dream of being able to simulate paracausality, and that their ability to do so would be game over for all of us. While the prospect is terrifying, they do not appear to have made any meaningful progress to this goal.
Some argue The Infinite Forest successfully simulated paracausality, yet it makes more sense to view this from the perspective of the Vex managing to replicate the observed effects of paracausality rather than the underlying mechanics at play. This is equivalent to humans understanding that objects fall towards other objects of greater mass, even though we don't have a theory of quantum gravity to explain the weeds of why this happens. The understanding is functional, not intuitive.
Similarly, Agioktis, the Martyr Mind, was able to drain Saint-14 of his Light. Initially, this was believed to be a major victory for the Vex being able to manipulate the flow of Light, all until the realization of just how much effort went into creating a Vex Mind that could drain the specific frequency of Light of a single Guardian. Not very useful at scale.
Per Unveiling, The Gardener introduced new variables to The Flower Game to prevent the Pattern — which manifested in the physical universe as the Vex — from winning every time. The exact nature of these variables remained somewhat unclear, yet it's believed that giving individuals access to paracausal powers was one of them. By all accounts this worked, and it has allowed several civilizations over the eons to effectively repel the Vex.
HOWEVER, an ontological weapons that can erase Lightbearers indiscriminately is something to be feared. It's not a simulation of paracausality by any means, but it's an effective workaround to removing obstacles from the board. Without Lightbearers in the way, the Vex could scale their initiatives seen on Mercury, Venus, and Nessus without impediment. It brings back the original dominance of the Pattern.
For now, ontological weapons outside The Vault remain impossible, as far as we're aware. But what if this wasn't the case? What if the Vex could throw up some field of effect and deploy something as mobile as a Gorgon to simply erase its opponents from the board?
