What is Quria? Quria, Blade Transform was a mind built by the Vex to understand and utilize the Sword logic, when the Vex entered Oryx's ascendent realm, thanks to Crota and Savathûn. He realized that if he killed everything, he would become strong. So he slew a lot of Oryx's forces, and became a major force in Oryx's realm. Eventually, however, Oryx cornered Quria. As a last-ditch effort, he tried to simulate Oryx, but he couldn't understand the Darkness within him, or the worm. So he made an Aurash. Finally, after having a little conversation with her, Oryx took Quria. The taken Quria is then gifted to Savathûn, his sister, known for being cunning. Oryx says that Quria has a bit of will left, so it can surprise her.
