KINGSGLAIVE: FINAL FANTASY XV

Final Fantasy XV takes place on the Earth-like world of Eos,[16] which is divided between four nations: Lucis, Accordo, Tenebrae and Niflheim. Lucis, occupying a whole landmass, possesses a magical artifact known as the Crystal, gifted to the reigning Caelum dynasty by the world's deities in antiquity and accessed through the hereditary Ring of the Lucii. Accordo, located in the southern part of Eos, is an island nation formed through a union of free trading cities. The western continent is home to the technologically-advanced empire of Niflheim and the nation of Tenebrae, which is ruled by the Oracle—a priestess who can commune with the gods. The Oracle's main task is curing the Starscourge, a plague that absorbs all natural light and turns those infected into nocturnal monsters known as Daemons.[17][18][19]: 318–319  Central to the lore of Eos are the Astrals, six divine beings who serve as the guardians of the natural world and are based on summoned monsters from the Final Fantasyseries;[6][20][21] and the True King, a legendary figure prophesied to appear when the Starscourge threatens to plunge Eos into eternal night.[22] A key part of Eos's backstory is the Great War of Old, a conflict born when the ancient human civilization of Solheim turned on the Astrals and their patron Ifrit; his subsequent attempt to destroy humanity defied the Astrals' duty to protect Eos, forcing their leader Bahamut to kill him. This conflict is implied to have caused the spread of the Starscourge across the planet, hastening the fall of Solheim.[19]: 318–319 [22] For centuries, Lucis has been at war with the militaristic Niflheim, who seek to emulate Solheim's glory. To that end Niflheim has subjugated most of Eos, including Accordo and Tenebrae; Tenebrae retains limited political autonomy due to the Oracle's influence. Only Lucis's capital city of Insomnia remains unconquered due to the use of the Crystal's power, which is slowly draining the current king's life force.
