The rise of Leo Principality

A modern-day programmer, Michael, is thrust into the body of Alexius, the powerless Crown Prince Regent of the failing Principality of Leo. In a medieval world teetering on the brink of chaos, besieged by aggressive empires, scheming republics, monstrous hordes, and corrupt internal factions, Michael must leverage his wits, fragmented princely memories, and a mysterious "System" to seize true power, save his nation from annihilation, and carve out a new destiny as a conqueror.
