The military might of the Empire was tested long ago when the forces of Evil landed on the shores of Auropa with every intent to slaughter each citizen and ravage the lands. 
When these foul creatures started to form upon the sands of the coastline, Dwarven artillery blasted their ships to pieces while Human gunners and Elven archers ripped through the lines of the invaders. Draph heavy infantry punched through the dazed brutes causing them to flee and rout toward the sea. Men in Calvary units quickly cut down those who ran. By the end, the Empire only had a little over a hundred casualties. Simultaneously, the bodies of the invading forces of Evil piled high with tens of thousands of dead stacked on top of each other, which was not even close to the number of those who died aboard within the fleet. Only one ship of the thousands escaped holding less than a hundred surviving Invaders. 

After the invasion, the Emperor gathered up ten-thousand troops and followed the runaways back to where they came from in a land known as Naggarok. Here the Emperor led a grand crusade across the entire continent of Naggarok, fighting all sorts of creatures from feral monsters, Beast men, Lizardmen, Rat men, Orcs, Goblins, Trolls, Giants, the undead, and even demons. Many of the savage brutes were cut down with ease by the Empire. In the end, it was a resounding success. The creatures of Naggarok had lost millions, and this defeat burned into their racial memory forever. The undead was put to rest, and almost every demon was wiped out of existence. This victory ensured that no one would dare attack the Empire ever again, and the Emperor led his troops back to Auropa, where the living celebrated, and their dead were given proper burials.
