Transmigrated into a disgraced prince framed for treason, Leon is exiled to a ruined northern keep with 300 men and a territory-building system. He opens the gates to starving refugees, turns grain into loyalty, builds cement walls, waterwheels and steam ships, and defeats bandits, a usurper and a continental alliance—not by conquest, but by trade, currency and full bellies. Offered the throne, he refuses, choosing to guard the North forever.
