Fantasy

After dying from exhaustion in his first life, Lucien awakens in a world of magic and nobles as the heir of the powerful House Valcroix. But after a failed awakening caused by hidden poisoning, he is branded worthless and exiled to the frozen northern frontier.
    There, among ancient ruins, deadly winter beasts, and political conspiracies, Lucien discovers a mysterious system that grants him knowledge and power beyond this world’s understanding.
    While kingdoms still rely on swords and magic, Lucien begins building steel furnaces, firearms, cannons, and an industrial empire beneath the snow-covered mountains of Elarion.
    With loyal retainers, stubborn dwarves, a legendary mage, and an arrogant golden dragon at his side, the once-forgotten exile slowly rises into a force capable of changing the world itself.
