[quote]So essentially if left unchecked the vex could reach ascendant hive power and/or Taken strength?[/quote] Yup. Although Oryx put a stop to Quria, he gave it to his sister to study because he thought its attempts comical. Its also worth noting that sword-logic dictates we, the guardian, are now ascendant Hive because we, already deemed gods by the Deep because we defeated Atheon, beat Oryx. [quote]In the paradox mission we learn from preadyth (in the daily heroic only part of the mission) that the taken vex is their unavoidable future in which atheons purpose was to avert?[/quote] Praedyth's Vision [from the FWC golden age device?] was of unrelenting Darkness. We were essentially seeing his vision a reality when fighting all of those Taken before getting the chest. The rest of that mission talks about why the Vex joined the Darkness. They saw their own demise. That is why they tried to write themselves as a law of reality with the Vault of Glass, because laws are constants. The City put a stop to that, so the Vex turned to something that promised survival, the Darkness's Sword-Logic.
