Are we placing ourself in the existence of the Vex? Even if this is a simulation. We can't stop the Vex from reaching their outcome. They are ready for anything. But what if we are a part of that outcome. We made Aegis exist in them, why not ourself? It would be hard. We would have to kill a Vex mind outside of all these simulations. A real Vex. All we see and do is faked. We are in a Vex simulation. But we are braking out. We have learned to exist in the Vex. What I mean is they can't get rid of us. Remember the relic from the vault of glass. That was part of the Vault. We remember someone who was deleted, gone. We have killed a Hive god which will give us access to tools that brake causality. Logic says a computer simulation can't leave and be real. But we have the tools to leave. If we leave and are able to kill a real Vex mind. As in a Atheon from the non-Vex made world, we would be able to become part of the Vex ending. They have a plan for everything, but we can become part of that plan. Would that make an interesting raid? Is Deej even real? Who knows! All we know is how to beat the Vex. Edit one: I'm literally just speculating ideas. I know we can't be simulated. But what if parts of this world are simulated? Edit two: just realized I don't have all the Vex simulation card story.
