Wait, y'all remember the chapter where the mythical Goddess died? If some deities died, they'll explode, how powerful they are, the bigger and powerful the explosion can be. Ramuh here is probably in his full state or a bit less. If he dies, then he'll explode like a nuclear bomb. Then the Protectorate will erased from the map for good. As for the railgun, I bet it is used and kill Ramuh. Remember the chapter Ford said that the railgun's projectile could peirce through the atmosphere and create a massive shockwave anything it flew, if it used, it could peirce through the sea of clouds and create a path destroying the clouds. I theorize that the endzone will no longer anymore.
