Biography
When the Hive first met the Vex after Crota used his sword to tear open a portal into another dimension, the Vex became intrigued by the paracausal powers that Oryx possessed, specifically, the Darkness. Attempting to solve the problem of paracausality, the Vex created the Axis Mind Quria, Blade Transform. Quria's solution to the problem of the Darkness was to simply kill off the Hive, in accordance to the Sword Logic.
