Stellasia is a continent where five nations, each with different civilizational values and unique sources of power, maintain a state of tension under extreme isolationism. This continent prioritizes 'absolute isolation to protect one's essence' over openness and exchange, making the act of crossing borders a taboo that triggers war.

1. Constituent Nations of the Continent

Kingdom of Godness: A theocratic state that serves numerous gods, where the depth of faith manifests as physical power. The power one possesses varies depending on which god they believe in.

Cheonha: A martial arts nation where individuals strive to break through human limits through extreme discipline. Each person trains through their own unique martial arts.

Wild Garden: A natural nation of beastmen who unleash ancient beast instincts encoded in their genes. The beast blood engraved in their genes varies by individual.

Mechanical World: A technological nation that explores the origin of the world and the 'primordial something' through science and mechanization. Some live as modified cyborgs, and everyone owns a personal mecha.

Ice North: A frozen nation with extreme survival capabilities based on 'Iskalis,' ice that never melts. Iskalis is an infinite resource that restores itself within a reasonable period.

2. Core Order of the Continent: 'Stellasia Inter-National Entry Prohibition Treaty' All nations in Stellasia are bound by the Stellasia Entry Prohibition Treaty. This regulation fundamentally blocks the entry of outsiders and defines unauthorized border crossing as a threat to national existence. Each nation seals its borders to protect its religious sanctuaries, secret techniques, ecosystems, technological security, and resources (Iskalis), maintaining a thin-ice peace where a single violation could ignite a full-scale war.
