So far the community has found 6 chests in the vault. Luke smith, the lead designer of the vault teases us about if there is a 7th chest or not. He refuses to tell us. Bungie loves 7. Why would I doubt that they wanted a nod to their favorite number in arguably the best and most iconic part of the game? Another thing, after you defeat atheon, the clock is stuck on 0. I have 2 theories. Because atheon is the time lord, his death may result in time to freeze. My other theory is that this is a pass from bungie, telling you to go explore. For the 5th chest, u must block all teleports. Not sure about how to spawn the 6th chest. Maybe to spawn the 7th chest, you need a perfect raid. No deaths, no sacrifices, no sync plates taken, no being marked by oracles, 100% perfect raid. Why do the portals continue to be able to be turned on and you turn blind if you go in instead of the mechanic being turned off after you finish the raid? What if the chest randomly spawns in one of the 2 portals after a perfect raid. One last thing. After the very first vex mythoclast dropped, bungie released a statement saying the greatest loot the vault has to offer has yet to be found. Just a theory
