"The Mythoclast is a Vex instrument from some far-flung corner of time and space, mysteriously fit for human hands. ***** Its origins, mechanism of action, and ultimate purpose remain unknown. Perhaps it will reveal itself to you, in time...***" Perhaps, the Vex mythoclast t is a key of some sort? FYI - Venus portal has a door similar to Atheons entrance. Or maybe we need to do something within the past and present portals to activate let's say....an unused portal? I am interested in exploring (PSN) Vex Grimore.
