The Salvation of the Empires TSE

Decades ago empires fell one after another, as they battled each other, however one rose to be strongest of all. However, they lost many soldiers and two generals. Now they were reborn into this world once more, would they fight alongside each other once more against a new threat? Would they meet the same fate as their previous life's? If so, would they remember each other or who they used to be?
