I'm not so sure. If Shantotto traveled to another place, that happened to be Eorzea, of our own volition, she had to open a passage through the Void. The same with Lightning, but she went to the wrong place.

Also, seeing how Black Magic dabbles into the Void and Xantes' pack, I would not put it beyond our ability to step into the Void at will.

They said they would better explain those characters appearance later, the Void and how it links to Hydaelyn. That is where the World of Darkness comes in.
