Surely someone before now, especially with the reveal of the shelter containing the dark world, consider that there's just a massive dark world going all through the underground of hometown?

In other words, when characters are creating dark fountains, they're really just piercing the ground normally, but the darkness from the dark world underneath seeps in through the crack created? It would essentially explain Ralsei travelling, he's just going underground, travelling via the darkness there, and popping out the other end.
