Then what was the point of mentioning that the vex were capable of locking so and so place out of space-time? You could call the black garden a simulation, sure Because I have no idea what to call a place that have been removed from space-time But I don't believe it to be just an unreal scenario we've witnessed The black garden is (or was) as real as you and I. Now that we've destroyed it, the vex had to either A.) revive the one entity they didn't understand and actually feared B.) return to their original purpose, whatever that was
