im on xbox one and was playing VoG a few days ago and found a secret that's gunna stop all the searching and finally end the rumours! I'll post the details in the morning! 'EDIT' Right, at the very end of VoG i did it on HM btw, my full fireteam had finished defeating Atheon, as the game doesn't take you straight to orbit i waited until everyone left the game. As i was interested in a Grimoire Card(Probably Misspelled) that says something about opening the Vault while being alone but also not alone at the same time. As the last team mate left i noticed that i had a Time's Vengeance Perk so i rushed to the main door and pulled out my ghost to open the door and ran towards the cliff, as i got towards the end i saw an illuminated pillar so i jumped on and it took me to a vex gate which was glowing i entered the gate and there was a single gateway thing(like the ones that open Venus and Mars or Past and Present/Future at the gatekeeper cp) i stood on it and exited the gateway and jumped back on the Pillar to Atheon Room, when i entered i saw a gate at the far back which took me somewhere i have never been before i believe its at the far back behind where Atheon enters the Vault. I followed the stairs up to another Doorway which i couldn't seen to open but know that the true Vault is inside as there's huge Glass Shard things spinning either side of the door.. That's my findings. Hope you guys manage to get there too Message me if your stuck I'll try helping you out Thanks for the non-haters Peace. 'Edit' I have received shit loads of grief on this post, mostly people trolling my post and then trying to call me a troll.. The thing is that it worked for me and now has worked for other people.. So look into things before posting hate on other people's topic's, especially those trying to help!. Thanks to all the people who've posted that they've also found this!
