Yeah, this is all because of the traveler. It isn't going down till the last game and or its subsequent dlc. If we destroy the traveler now, and discover all its secrets. (Thanks to grimoire we basically know everything minus the birth of the traveler and who made it) then what the hell do we fill all the other games with? The cabal love to blow shit up, so it's probably gonna be disarming a bomb or raiding a vault for weapons.
