Right. Last night me and my bro really went crazy with the whole theory and discovered a few things. People think and it is described in the lore somewhere that the Vex Mythoclast is a Key, it's also said the the pocket infinity is a human attempt at making a Vex Mythoclast. We've also found the abandoned portal that's just outside to the entrance to Aetheon. There's also the light's that change from red to green when shot. Also lets not forget about the Gorgons. Now we put all of this together and you'll be surprised at the outcome. Firstly we killed all the Gorgons after realising what the pattern was, we then had one person stand outside of Aetheon entrance actually in the abandoned portals entrance, while he was there we turned all the red lights green using the mythoclast and pocket infinity. We then left him out side and killed he gatekeeper. This is what happened next - ABSOLUTELY NOTHING. Give it up, the guy said he misheard the question.
