Over the past two centuries, mankind has tamed its basest instincts, and reached the starsBut suppose it hadnt happened that way at all?
Suppose instead humanitys darkest impulses, its most savage, animalistic desires had triumphed?
Suppose that the empire mankind made out in the stars was one ruled by terror, where only those willing to brutalize their own kind and their neighbors could survive?One hundred years ago, four crewmembers of the U.S.S. Enterprise crossed the dimensional barrier and found just such an empire.
A mirror image of their own universe, populated by nightmare duplicates of their shipmates.
Or so they thought.But now the scientists of that empire have found a doorway into our universe.
