Solfleet Intelligence Special Agent Dylan Graves has passed though the ancient Tor'Roshan device known as a Portal and traveled 22 years into Earth's past. His mission: Infiltrate the staff of the Mars Orbital Shipyard and ensure the vessel suspected of being instrumental in the destruction of the starcruiser Excalibur in that time period remains docked there. Prevent the destruction of the Excalibur, thus altering specific events in the future and hopefully changing the outcome of the war against the Veshtonn Empire-a war that Earth and the Coalition were on the verge of losing. It is a vital mission, one that he must complete successfully. But altering some events without interfering in others proves more difficult than he ever expected, and time after time he finds that his mere presence has influence, whether he wants it to or not. But still there is the mission.
