Enter a new Europe, a different Europe. The Romans never ascend to their full potential, Caesar never comes to power, Carthage and Rome never go to war. The United Gaulic empire rises, Northern Germanic tribes form their own Unions, the Swedes, Fins, Norse, and Danes all rise, the Dutch Republic, taking its ideals from old Roman government begins its reign early, deciding which to side with, as it is the most powerful Germanic tribe. Vikings are early, as early as the 2nd Century, the first Norse war follows the Danes, Swedes and Norse fighting eachother, they all have territories in Europe that they wish were theirs. You must fight to the death, or you will be captured and executed.
P.S this is my first book. Please be judgemental, I want progressive critiscism thrown at me from everywhere
