The Foolish Prince, Aleuas Eins, left the kingdom when he was only twelve years old, as his naïve wish to see more of the world coincided with his stature as merely a second Prince of the Eins Royal Family. Five years later, the country is struck by war, as the invading Rorldon Empire enters swaths of land across the Great Alm with a large army, leaving Aleuas stuck a sea away in a large island nation. After five grueling years of war, an underground organization takes roots in the lands, as a young and cunning girl infiltrates kingdoms and empires, tipping the gentle balance of power to the way she imagined. With her help, Eins survives the invasion. Surviving all this despite, or because of, their enemies, the war-torn Kingdom of Eins is left without its King after a gruesome civil war, and it is up to Prince Aleuas to step forth to try his best to save his kingdom.
