Final Fantasy XV is an action RPG developed and published by Square Enix for the PlayStation 4 and Xbox One. It shares a thematic connection with Fabula Nova Crystallis Final Fantasy, a subseries of games linked by a common mythos which includes Final Fantasy XIII and Final Fantasy Type-0. Final Fantasy XV takes place in Eos, a world similar to modern-day Earth, where all the world's countries—bar the kingdom of Lucis—are under the dominion of the empire of Niflheim. Noctis Lucis Caelum, heir to the Lucian throne, is driven from his home when Niflheim invades Lucis on the eve of peace negotiations between the two nations. Now on the run with his companions, Noctis begins to work towards defeating the forces of Niflheim and rescuing the crystal from their control.
