On your second post there is one inconsistency I believe to exist and it is that us humans can survive time travel (we did it in VoG), and are you sure Kabr forged the shield from a gorgon? I think the shield is Kabr or at least has fragments of his consciousness... "Guardians make their own fate" now who said that? The shield maybe, and other weird quotes during Atheon fight. However the Vex do seem to have a plan for you, after all the Vex Mythoclast is mysteriously fit for human hands
