That'd be cool to see. Almost like Lucent Hive but for vex. And especially after one of the devs hinted at the Vex playing a bigger role after the final shape, We could potentially see them experimenting and successfully simulating the light. And to add to your new faction of Midexial Vex, perhaps we could also see inspiration taken from the whole "biblically accurate angel" stuff. This could come in the form of a new elite unit of lightbearer vex that harnesses simulated light that has the appearance of a biblically accurate angel with all the rings floating around it. Perhaps it could act similar to a servitor but a vex version where it can guard other units with its simulated light. Maybe it can even come back to life if it's not finished off.
