Final Fantasy XV: Episode Ardyn - Prologue

2000 years before the fall of Insomnia, Ardyn Lucis Caelum travels among people afflicted by a terrible plague. He saves them by drawing their corruption into his own body, while his brother Somnus chooses to destroy the infected instead.

The brothers’ opposing convictions collide with the question of who will become king. Beside Ardyn stands his beloved Aera, an oracle awaiting the gods’ decision. As faith, ambition, and compassion pull them in different directions, the healer’s gift becomes inseparable from the tragedy approaching him.
