In a fantasy world ruled by kings and queens possessing great magical power, Kant Icurus Maybale is the only prince on the Aceaton Continent who does not possess magic. However, what he does possess, that nobody else does, is his past memories of the time when he was a Mechanical Engineer on Earth. With nothing but knowledge, brains, and wisdom, he dares to bring this medieval-esque fantasy world into the industrial era, and gain unimaginable wealth and power. Along the way, powerful forces that feel threatened by his rise in dominance will do whatever it takes to bring him down! Will he be able to conquer the continent, and potentially the world, to usher in a new age, or will he get crushed by the existing world order?
