Zerstorung durch Fortschritte der Technologie

"We think we understand reality, but our universe is only one of many. The unknown truth is that the way to travel between them has already been discovered by beings like us, but whose history is slightly ahead of our own. The negative aspects of such visitations will be irreversible both to our world and to theirs. It will begin with a series of unnatural occurrences, difficult to notice at first, but growing not unlike a cancer until a simple fact becomes undeniable: only one world will survive. And it will be either us...or them."
