A wise man once said all roads lead to Rome. He didn’t know how right he was.Ripped away from the battlefield, Tiberius and his six thousand Roman Legionnaires unexpectedly find themselves stranded in a foreign land of magic and witchcraft. With no way home, their path forward is obvious: conquer everything in sight.Much to the chagrin of Marcus—the poor, unsuspecting bard who summoned them.But taking over the world is not so easy. In order to stake their claim, the Legion will need to learn how to navigate the strange magics and abilities this new world has granted them. Abilities which, upon closer inspection, may prove the seed for a legend in the making…The dawn of a new empire looms on the horizon. Rome will rise anew as they seize cities, battle armies, and expand their territory across this strange and fantastical world. All the while, Marcus will need to figure out how to mitigate the force of nature he's unleashed upon his woefully unprepared world. That, or simply enjoy the front row seat to an epic in the making. Someone will need to tell the story, and who better aside from him?The die has been cast. The aqueducts are being built. And Rome will once more see glory.
