Output (English): During a visit to Tenebrae, Regis and Noctis—who is recuperating from a neardeath experience—are targeted for assassination by Niflheim. Tenebrae is subsequently attacked, and in the invasion Queen Sylva is killed by Niflheims General Glauca. Regis attempts to flee with Lunafreya, but she decides to stay with her brother Ravus; both become subjects under Niflheims rule. Twelve years later, the Kingsglaive fight to protect Luciss borders from attacks by Niflheims Magitek army and Daemons, unnatural monsters tamed for military use. During one such operation, Nyx Ulric defies his orders to withdraw to rescue his friend Libertus from a Daemon. Regis, whose magic powers the Wall and is growing weaker due to advancing age, accepts Imperial Chancellor Ardyn Izunias offer of peace. This causes dissension among the Kingsglaive, who feel Regis is abandoning their families. Two days before the treaty is to be signed, Kingsglaive member Crowe is sent on a mission to escort Lunafreya to Lucis, but is killed en route. Her death causes Libertus to leave the Kingsglaive and join a group of Lucian rebels. At a party dedicated to the signing of the treaty, attended by both Regis and Niflheims emperor Iedolas Aldercapt, Lunafreya meets with Nyx before being secretly abducted by Glauca. Nyx discovers this and finds that Niflheim has stationed their army outside Insomnia. Regis agrees to deploy the Kingsglaive, although their commander Drautos has disappeared. While Nyx succeeds in rescuing Lunafreya, many of the Kingsglaive turn on him; Nyx, Lunafreya and rebel leader Luche Lazarus escape as the ship disintegrates. At the treatysigning ceremony, the Niflheim delegation springs a surprise attack and kills the ruling council, while their army enters by destroying the Wall with help from the rebels, who are subsequently massacred. Lunafreya and Nyx reach the Citadel just as Regis is battling Glauca. During the fight, Glauca cuts the Ring of the Lucii from Regiss hand. Ravus attempts to put on the Ring and claim its power, but it rejects him and destroys his arm before he can remove it. Nyx, Lunafreya and Regis retrieve the Ring and flee with Glauca in pursuit. Regis forces the two to go on without him, dying in his ensuing battle with Glauca. Aldercapt and Ardyn—having successfully stolen the Crystal—leave Insomnia to be destroyed by Niflheims Daemons. Summoned to the city plaza by a call from Drautos, Nyx and Lunafreya are cornered by Luche, who reveals himself to be Crowes killer. Luche almost kills Nyx before being tricked by Lunafreya into putting on the Ring, resulting in his death. Drautos then appears, but is attacked by Libertus, who reveals that Drautos is in fact Glauca. Just as Glauca is about to kill them, Nyx puts on the Ring. He is confronted by the spirits of the past kings of Lucis; initially rejected due to being not of their bloodline, his resolve and the threat to the Crystal persuade them to allow his use of their power at the cost of his life. After fending off Glauca, Nyx returns the Ring to Lunafreya before entrusting her to Libertus, telling them to flee. With the Rings borrowed power he engages Glauca in a titanic battle throughout Insomnia, animating the citys statues of past rulers, known as the Old Wall, to combat Niflheims Daemons. Their fight ends as dawn approaches, with Nyx mortally wounding Glauca; Nyx dies shortly after as payment for using the Rings power, wishing for Noctis to rule well in the future. In the aftermath, Libertus escorts Lunafreya out of the city, but she tells him to stay behind. Lunafreya then leaves with the Ring to find Noctis. In a postcredits scene, Noctis and his companions are en route to Altissia when their car breaks down, leading into the opening scenes of Final Fantasy XV.
