"The Vault of the Great Mind"Edit
Gunoor13, I know you insist on there being a Vault of the Great Mind in Curse of Osiris, but it just won't happen. Bungie already explicitly stated the endgame; we're going back to the Leviathan and that is all. It is what it is, but if you still have this idea in mind, you can always express it on our forums. Thanks for your cooperation.
