While nobles and priests laugh at his failed gift, he sketches a simple gazebo—and watches it appear in the real world. He soon realizes that his power is not meant for battle, but for creating entire cities from carefully designed blueprints. Starting with public fountains, shelters, and homes for the poor, Sihyeon gradually transforms forgotten land into thriving communities filled with schools, workshops, bridges, hospitals, markets, and beautiful public spaces. As craftsmen, engineers, scholars, soldiers, and refugees gather around him, the settlement of Seryon-dol grows into a city unlike anything the world has ever seen—one built for ordinary people instead of kings. But every new district he creates threatens the Great Houses that have monopolized architecture, land, and magical construction for centuries. When Sihyeon discovers that the world itself was never fully completed and that the northern lands are slowly disappearing into an ancient void, his mission expands far beyond city-building. To save millions of lives, he must finish the unfinished map left behind by the First Great Cartographer four hundred years ago and literally draw the missing parts of the world into existence. An epic kingdom-building fantasy about architecture, engineering, city planning, civilization building, leadership, and one ordinary designer who proves that the greatest heroes are not those who destroy kingdoms—but those who build them.
