Dude Sol is central to them. There is a possible reason they are Vex ships. Vault of Glass, their main hub. Infinite Forest, their only way to simulate paracausal entities and plot a future where they win (Dark Futures) Pyramidion, massive data storage network Multiple worlds mostly converted -Also a strange note. In the BoS the Hive that went into the Vex side of the gate lost power. So it’s possible Vex who gained power in the throneworld can’t travel in the Vex system without losing it. They might need to stay in the materialHence why they would need ships and require some form of paracausal power. Just spitballing that The plotting of survival is their main focus. We have all three primary functions of that job here in this system. The same system the final showdown is happening. The connection between Ghosts and the Vex is troubling. That the Vex think they share a common “home” is a serious [b]ref flag[/b]. Also they were able to fight in the throneworld because that space gave them the Sword Logic power. They don’t have it in the material plane. So their warriors won’t be as effective here (unless the power carries over. In which case they would have to hold them in reserve to protect their central locations. Can’t risk it for normal slugouts) Nah, they got a front row seat to the two main powers it opposes fighting each other to the death. This is a perfect setup for them to [i]manipulate[/i] us. They can’t fight us here like they could in the throneworld. So the next best step is brute force plotting a way out of the hole they are in. Which seems to be working since Curse tells us they have multiple ways to win.
