At the end of the Great War, 3 centuries ago, the societies and civilizations on Earth which still existed were in total chaos. Milennia of warfare for survival against the Forces of Darkness had taken their toll. The enemy was defeated and driven back into their own territories behind the Great Barrier, a gigantic wall of magical energies no dark magic can penetrate, not even the Lord Daemons were able to break this seal and use their magical powers to cause destruction on the other side. But victory came at a price, and while the dark forces were effectively sealed behind the barrier, only able to send their weaker troops through whenever they managed to conjure enough creatures again, the Forces of Light suffered from much greater losses.
Just like the enemy they were almost completely defeated. No fortresses remained intact, countless cities and settlements were destroyed, the noblest of the noble have fallen in battle and there were only little trails of order and leadership left.
