Crossing into Another World with an Empire

The protagonist carries an alternate-dimensional territory that can build structures and recruit subordinates into the real world. He inexplicably transmigrates to a world that has only recently completed its First Industrial Revolution. There, he accidentally discovers that his alternate-dimensional territory has merged elements from the three major game series on his computer in his previous life: Age of Empires, Mount & Blade, and Total War, combining them with the profession system of the other world. Human soldiers from the steam era are combined with this world’s unique profession system. The greenskins of the Eurobaro Continent and its vicious human lords remain in a savage feudal age, while humanity’s desire for magic stones has already brought the colonial advance to the magic-rich Eurobaro Continent. What will happen when elves, beastmen, Chaos humans, monstrous beasts, ratmen, lizardmen, and other nonhuman races collide with a human steam world populated by people with specialized professions?
