ɴ/High Kingdoms

The High Kingdoms of Oikia and Monoikos is a country (Exteras:, abbreviated as the HK, Exteras: ), predominantly referred to as the High Kingdoms, is a union of 64 countries across Oikia, the majority of which are located in Alaxia.

Originally founded in 10,898 BKY by Auster, due to his status as King of the Gods, the High Kingdoms was the most powerful political entity on Oikia. Its authority would eventually be challenged by the First Order of Cralas, led by his son Isme-ma, beginning the Kataric Wars. Lasting several hundred years, the wars would have cataclysmic consequences for the inhabitants of Oikia, and by its closure the planet's surface was largely uninhabitable, aside from territories within the Vamu. The High Kingdoms would effectively cease to exist upon the killing of Auster by Boka.

Multiple attempts to revive the High Kingdoms upon its collapse in the Great Catastrophe in 10,466 BKY have occurred throughout history. First during the Futile Wars when the last vestiges of civilisation continued to compete against one another. Following the Vamu's terraformation of Oikia, the Anternian hero, Lucas, made the first attempt. Having founded the city of Lucero in 247 BKY, he sought to create an empire spanning all of the southern hemisphere in the name of Auster. His successors would eventually form the Anternian Empire in 200 KY, by Sublimis. Its maximum extent in the 590s KY would see it span from Jezazra to Vreimer.

Refounded in 2503 upon the ratification of the Treaty of Eutopos, signed by 25 founder states, the High Kingdoms established itself as the co-de-facto world government alongside the International Concord. Since 2503, its membership has since expanded to 64, incorporating significant Bokanist, Miyanu and Corporian populations. Auster II led the revival of the nation, rebecoming Emperor upon its founding, and leading until 2517 with his disappearance. Since then, Richard I has ruled in his stead. The High Kingdoms boasts a population of 3,653 million, the most populous nation in the world, it also possesses the most massive economy. In terms of space presence, it contains the second largest of, with 6,456,000 citizens in permanent habitation outside Oikia. It is also one of the five states to possess a unique seat on the Consortium of Planet's Interstellar Council.
