The stars are aligning and the "Great Old Ones" sense their opportunity is at hand.  Conquest of Earth and the subjugation of the human race is their ultimate goal.

​

Three groups of heroes, investigators, and outlaws must work across the span of history to thwart their evil intentions.  Unknown to each other and in their own times, they seek to solve the puzzle that will prevent the return of Earth's ancient masters. 

 

But as each piece is placed, the Old Ones grow stronger, and the fate of humanity becomes less and less certain.
