Story
After Lady Lunafreya Nox Fleuret is believed to have died in the attack on Lucis, Prince Noctis's party travels to see her in Altissia where to two were to be wed. Lucis was attacked by Niflheim during a treaty-signing ceremony, during which Noctis and his friends were heading to Altissia for the two to get married. As the ferry from Galdin Quay doesn't run under the present circumstances, Noctis has the late King Regis's friend Cid Sophiar take them on King Regis's old ship. They use Cid's old travek documents to get past the border control, and Noctis and his friends head off to find Luna.

Luna is accompanied by Gentiana, and is under watch by both city officials and Imperial forces, as part of a compromise for the summoning ritual to take place. Luna wishes to rouse the sea goddess, Leviathan to have her grant her blessing to Noctis. She was met by her brother Ravus Nox Fleuret who works for the Empire as the high commander. Ravus disagrees with Luna's conviction to help Noctis at the cost of her own health, not believing the prince to be the True King. Nevertheless he hides her from Niflheim so she can continue, and urges her to deliver the Ring of the Lucii to Noctis by herself when she begs him to take on the task. Ravus visits the Altissia church and Chancellor Ardyn Izunia asks if he has had the chance to see Luna, but Ravus answers no.

The people of Altissia are peaceful and have been long uninvolved in the global conflict. Though considered part of the Empire by Niflheim, Altissia has its own government. To this end, the first secretary is cautious to grant Luna succor, and is reluctant to allow her to commune with the sea goddess after the destruction that awakening Titan brought to Lucis. After learning the king of Lucis is in Altissia, the first secretary seeks him out at a local restaurant and asks him to visit her manor for negotiations. Noctis must convince the first secretary to allow Luna to go through with the ritual, presenting himself in a way befitting of a king.

To invoke Leviathan, Altissia keeps a sacred trident that they allow Luna to use in the ritual of communion. As a commotion is expected, Noctis's vassals are put on evacuation duty while he prepares to forge a covenant with Leviathan with Luna's aid. The Empire assaults the city as Leviathan is summoned, angering the astral goddess and Luna cannot speak sense to her. Destroying Leviathan is Ravus's mission as the high commander, but he is pursuing it for personal reasons to save his sister. Leviathan goes on a rampage, and the city is rocked by surging waves and invaded by Imperial forces. Chancellor Ardyn stabs Luna with the intent for Noctis to witness it. Luna is still able to call upon the past kings of Lucis using the trident, and Noctis is granted power from the kings of old to put a stop to Leviathan. After Noctis wounds Leviathan, Titan appears from beneath the waves and the gods' clash sends out a tidal wave that destroys the majority of the city.

Leviathan accepts a covenant with Noctis and disappears. Noctis is left lying on a piece of broken pier when Luna crawls over to him and heals him with her last strength. Before dying, Luna passes on the Ring of the Lucii to Noctis who awakens in Altissia days later to hear the sad news and to discover his friend Ignis Scientia was injured during the battles and has lost his vision. Noctis leaves Altissia and heads toward the Imperial capital of Gralea to find the stolen Crystal of Lucis and save the world from the forces of darkness.

After Noctis disappears Starscourge takes over the world and the sun doesn't rise again. Altissia becomes disconnected from the Empire, but is also largely taken over by daemons. The people of Altissia, along with people from many other lands, congregate at Lestallum in former Lucis territory where the power plant keeps the daemons at bay.

Totomostro Arena
The coliseum in Altissia is a place where the player can play a minigame where monsters fight against each other, and the player participates by betting on the winner. The developers are considering adding more content there post-launch.

The Cursed Canvas
In a quest given by Vyv, a journalist in Lestallum, the party heads out to take a photo of a haunted painting called Lakshmi. The player can accept the hunt for it from Wesker's restaurant. The painting is under the first secretary's manor. The quest is an allusion to Final Fantasy VI, that also had a haunted painting.
