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

1. Constituent Nations

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

Cheonha: A martial 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 beast-kin who unleash ancient beast instincts engraved in their DNA. The beast blood inherited varies by lineage.

Mechanical World: A technological nation that explores the origin of the world and the 'first something' through science and mechanization. Some live as cyborgs, and most own 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 over time.

2. Core Order: 'Stellasia Inter-National Non-Entry Treaty' All nations in Stellasia are bound by a non-entry 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 warerous peace on thin ice.
