Has anyone explored the alternate or "secret" passage to the Templar's well for a hidden chest? (the passage underneath where the first chest is). I'm wondering why that passage is there if not to provide another chest? If so, that means you must do something in the first stage to trigger it. I'm wondering whether you need to not let the Vex take a plate (and probably not die). And then there's the question of where it's located... Edit: added a link to a video of what I'm talking about. Not my video, just one I found on YouTube.
