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

1. Constituent Nations

Godness Kingdom: A theocracy 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.

Tenka: 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 nature nation of beastkin who release the instincts of ancient beasts engraved in their genes. The animal blood etched into their DNA 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: 'The 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 fragile peace where a single violation could ignite a full-scale war.
