TO: TIME LORD
Date: January 1st, 2999 A.D.
FROM: A. QUANTUM, CHIEF SCIENTIST
MB TIME TRAVEL RESEARCH CENTER
Welcome, Time Lord. We are unable to greet your personally; the Research Center is under alien attack and all personnel are being evacuated.
You are about to embark on a life-threatening quest to prevent the planet Drakkon from conquering Earth. The Drakkons possess the most advanced time travel technology in our solar system. As you read this, Drakkon lords are forming powerful alliances in 4 historical time zones. If their armies succeed in altering our history, the Drakkons will easily defeat us in the present. Earth will become a mining colony, and its people slaves.
To win this war, you must revisit the past and vanquish the enemy. But our time travel system is crude and limited; it can remain operational for only 1 year. Complete your mission before January 1st, 3000 A.D. - or you will self- destruct with the system.
