Is the Black Garden an isolated pocket dimension simulated by the Vex, or something else? I'm guessing it's not "the" Garden, like winnower and gardener, since they seem to be incorporeal, and so does "The Garden". Next, why are the Vex so interested in the Black Garden, and does the "Black" part signify that it was created through Darkness, or meant to be a Darkness version of something else? Following that, why did the Vex create the Black Heart inside the Garden, specifically, and not somewhere else? At the end of "The Black Garden" campaign mission, we destroy the Black Heart, and Ghost mentions "we're back on Mars"; I assumed the Garden could only be entered through trans-dimensional access points (like in the Tenebrous Tunnels mission), and wasn't actually attached to a physical space (similar to the Vex Net or Ascendant Plane), so was this a continuity error, maybe a retconned concept? Now for the Vex, why is their only goal to "make everything Vex"? Did they learn this "final shape" dogma from the Hive or Witness maybe, was it always their goal? And why? Why do the Vex never interact with Earth [when they are prevalent nearly everyplace else], exept for the friendly Harpy, and the time they were essentially welcomed in by Lakshmi? The Vex continue to reside in Sol, and continue to initiate conflict: why don't they leave, and why don't they deploy heavy combat units if they insist on staying? They seem to be entirely incapable of defeating The Guardian and won't accomplish most of their goals because of them. Next up, why haven't the Vex tried to construct an Agioktis type unit to trap The Guardian and drain their power? I believe it was mentioned that it took centuries to construct, but can't the Vex just pull the design of this unit from somewhere and repurpose it, or replicate its ability to drain Light? What is the most heavily Vex infested planet in Sol that we know of? Why do they chose to focus some planets and moons more than others, and why do they need to enact "Convergence"? Finally, why aren't the Vex taking advantage of Darkness? They could incorporate Stasis and Strand into their weaponry, but they don't seem to want to, or maybe aren't able?
