Noctis and his three friends begin their journey to Altissia, the capital of Accordo, where Noctis's wedding to Lunafreya will take place. Finding the local boat services stopped, they receive news of Niflheim's attack on the city of Insomnia and theft of the Crystal; King Regis has been assassinated, and both Noctis and Lunafreya are declared dead. Meeting up with Cor, Noctis is tasked with retrieving the Royal Arms—the magical weapons of past Lucian kings—to rescue the Crystal and reclaim his throne. While staying in the city of Lestallum with Iris, Noctis is contacted by the Astral Titan; encouraged by Ardyn, Noctis endures Titan's trial and earns his power, learning that Lunafreya is traveling ahead of Noctis to awaken the Astrals from their slumber. The group continues to travel across Lucis, retrieving the Royal Arms and meeting the Astral Ramuh with assistance from Gentiana. He is also confronted by a hostile Ravus, spars with the mercenary Aranea, and receives further aid from Ardyn. The group eventually recover parts to repair Regis's old yacht, using it to travel to Altissia.
