Using time travel to fight wars seemed like the perfect way to solve the international disputes of the 27th Century: all the economic advantages of warfare without any of the devastation taking place in your own time. Multinational corporations and governments geared up for the effort, secure in the knowledge that since the past already happened, it could not be changed, so history was safe. Or was it? When it was discovered that history could, indeed, be changed as a result of interference from the future, it seemed too late to stop the Time Wars, so a special unit was created to “adjust” for historical disruptions and preserve the continuity of the timestream. But as if going back into the past on missions to preserve the future wasn’t challenging enough, now the elite First Division of the U.S. Army Temporal Corps faced a new and much more dangerous threat. A peaceful protest group had spun off a militant offshoot called the Timekeepers, radicals who believed the only way to stop the war machine was to create massive historical disruptions. A covert agent of Temporal Intelligence gave his life to warn of a terrorist plot by the Timekeepers, so Capt. Lucas Priest and Pfc. Finn Delaney are clocked back to 17th Century France, so they can join up with agents of the T.I.A. already in place to find out what the Timekeepers have planned. Their target could be Cardinal Richelieu, but it will be hard enough trying to figure out who their target is and how to stop them in a scenario where almost anyone could be a ringer, including a young Gascon named D’Artagnan and three of the King’s flamboyant musketeers.
