As a lot of you know, a secret area was discovered in the beta. This place was called the Seraphim Vault, but I most of the area was closed off inside so we have no idea what it's purpose is until we get the full game. Or so I thought, after looking at all the leaked missions, strikes, and raids, it seems that the vault is completely absent. What do you think this means? Could it that we don't know all the initial missions yet, it's a part of a future expansion pack, or is it a unfinished raid?
