2,000 years ago, an alien experiment to transport an intact planet Earth went horribly wrong. A duplicate Earth – Codenamed GEMINUS – was created and cast off into outer space. Frozen in time for nearly 8 centuries, GEMINUS was shielded from the rest of reality – until a freak accidental gap in spacetime caused the Star Cruiser Aquarius to crash on the lost planet. Trapped in the brutal world of the 12th century Holy Land, Billy Caudwell the teenage First Admiral, must repair the Aquarius and rebuild the derelict estate of Muscigny. However, an ambitious Templar Knight hatches a savage plan to depose the rightful King of Jerusalem and establish a new, entirely Christian kingdom by slaughtering every Jew and Muslim in the land. Billy must decide how to battle the renegade Templars and stop them from massacring thousands of innocent people.
