There are worlds beyond our own, don't you know? Some of them beneath us, and above ... way above. We might even be sharing the same space, those dimensions can get pretty tricky. The universe is ever expanding, and no one has returned from black holes ... or have they? Nonetheless, we are not alone. How many times must we tell you that? I've been there, to other worlds. I've seen them, those who are not quite human but human still. I am the Gatekeeper, and you've been warned.
Coming soon to your world.
