Forma: Forma is a planet several times larger than Earth located somewhere in the Milky Way. Its landmasses are concentrated in the northern latitudes, so the actual land area is similar to or smaller than Earth's. Most of the ecosystem is similar to Earth's, and Forma is inhabited by many intelligent life forms identical to humans and has a moon.

Geography of Forma: Most of the surface is covered with water, and the planet's internal density is lower than Earth's. Gravity is similar to Earth's. The atmosphere is similar to Earth's, but the ozone layer is thicker. Because of this, the primary races of Forma were white before the era of the ancient Libran Empire.

Oceans of Forma: There are two major oceans on Forma: the Libran Ocean and the Inanis Ocean.

Libran Ocean: A sea shaped like a lake surrounded by four continents, primarily used by ships worldwide.

Inanis Ocean: The largest sea of death on Forma. With no islands or continents in the middle, it was impossible to cross with pre-modern navigation technology. Most importantly, it is extremely dangerous as sea monsters live here. There are urban legends about a monster called Triphus.

Centaura Continent: The continent where the most conflicts and wars between nations occur. Due to the mountain range located in the Columba region, it is divided into North and South, leading to significant cultural differences.

• Northern Centaura: Not peaceful either, and relations between nations are not good. It includes the Republic of Ria, the Kingdom of Centauri, the United Territories of Columba, and the Kingdom of Grusa.

• Southern Centaura: The place with the most wars on the continent. It includes the Antares Empire, the Kingdom of Aquila, the Cetus Empire, the Corvus Confederacy, and the Kingdom of Vega.

Hydra Continent: Mostly occupied by the Orion Republic, so there have been fewer wars. It includes the Orion Republic, Hydrus, and the Canis Federation.

• Hydrus Subcontinent: A subcontinent in the north of the Hydra continent where the nation of Hydrus is located.

• Canis Subcontinent: Half of the sovereignty belongs to the Orion Republic and the other half to Canis. It is rich in oil and mineral resources.

Libra Continent: The Federation of Libra is the only nation, and it exhibits extreme weather conditions.

Ursa Continent: The Ursa Federation is the only nation.

There are parts where technology is more advanced than reality and parts where it lags behind. There are also differences in some historical aspects.

Black people face less discrimination than white people. This is because the primary ethnic group of the old Libran Empire was Black, giving them the title of "Rulers of the World." There is also a slur for white people called "Shiner."
