Niflheim The Empire of Niflheim is a nation in the world of Eos in " Final Fantasy XV " . It has achieved world domination bar the Kingdom of Lucis that has defended itself with the Crystal ' s power . Tenebrae has limited autonomy from Niflheim due to the Oracle Lady Lunafreya Nox Fleuret , who has the power to commune with the gods . Niflheim is technologically superior and more advanced than most nations of the world due to their knowledge of magitek . Automobiles originate from Niflheim , even though the cars made in Lucis are seemingly more advanced . Story . In the aftermath of the Great War of Old two thousand years ago , Niflheim was one of four countries created from the ashes of Solheim . Solheim was a civilization that dominated Eos and was overthrown by the astral god of fire , Ifrit . He had broken rank from the other astrals and turned on mankind . Aspiring to recreate the domination of the ancient civilization of Solheim , the Aldercapt family initiated its policy of expansion , proclaimed themselves as emperors of Niflheim , and began the prosecution of war on neighboring countries to annex them . In the year M . E . 359 , Niflheim conquered the land of Tenebrae , except the Fenestala Manor , home to the Oracle lineage of House Fleuret . In M . E . 501 , the imperial army discovered daemons , a life form unknown to them at the time . Circa M . E . 606 the conflict between Niflheim and the Lucian - Accordian Allied Forces continued , but the Lucian army was being overwhelmed by the weapons of the Empire . The Lucian king at the time erected the Wall around the whole of the Cavaugh region that includes the Crown City of Insomnia , and took up a siege position . By the year M . E . 725 , the entire world , bar the continent and country of Lucis , is under imperial rule , although Accordo is allowed relative autonomy . Emperor Iedolas Aldercapt , the long time ruler , once benevolent and loved by the masses , has begun the mass production of magitek soldiers for the forthcoming all - out war with Lucis . The magitek infantry was developed with knowledge on daemons provided by Ardyn Izunia , who was made the chancellor of Niflheim sometime after he arrived in Niflheim in 722 . The battle of Lucis and Niflheim lasted between 2 / 24 - 4 / 1 . Anticipating defeat by Niflheim ' s new magitek army , King Mors of Lucis ( Noctis ' s grandfather ) shrinks the magic barrier surrounding the kingdom to Insomnia ' s outer wall , strengthening it , but Niflheim breaches into the outlands of Lucis where they begin to build military bases . On M . E . 744 , King Regis from Lucis arrived in Tenebrae with his eight - year - old son Noctis Lucis Caelum for the latter to recuperate from an injury sustained from a daemon attack that had been orchestrated by the Empire . During their stay , Niflheim attacked the Fenestala Manor where the Tenebraean royal family lived to kill Regis and Noctis , and General Glauca murdered Queen Sylva in front of her children . Regis escaped with Noctis and the incident was covered up and the queen was reported to have perished in an accidental fire . The queen ' s children , Princess Lunafreya and Prince Ravus , fell into imperial custody . In the year M . E . 756 , the Emperor launches an attack on the capital of Lucis , Insomnia . The attack happens during a peace - treaty signing party which was supposed to settle the dispute , and have all of the Lucian outlands annexed to the Empire in exchange for peace . The treaty - signing was a cover for the true imperial objective : the invasion of Insomnia , the theft of the Crystal and Ring of the Lucii , and the conquest of Lucis . King Regis , his son Prince Noctis and Lady Lunafreya the Oracle are all reported dead . In truth , Luna escaped , and Noctis was not in the city when the attack took place , prompting him to try to rendezvous with Luna and start his quest to restore his kingdom and save the Crystal . Niflheim begins constructing military bases on Lucian territory and raids the town of Lestallum while looking for the exiled prince . Niflheim also attacks the astral god Titan in Cauthess , but Prince Noctis forges a covenant with the deity , and begins demolishing the newly - constructed bases with his friends . Aranea Highwind is a mercenary who used to work as a commodore in the imperial army . When Noctis ' s party meets her in Tenebrae she notes that the empire " went mad " ten years ago and began the process of mixing daemons with technology . Chancellor Ardyn Izunia had introduced to Verstael how to mate daemons with human fetus material , then attached to a robotic magitek trooper frame , and encased in armor . These magitek soldiers are , with natural daemons , used indiscriminately on the battlefield . After General Glauca ' s defeat at the battle of Insomnia , Ravus Nox Fleuret , the former prince of Tenebrae , becomes the new high commander of the imperial army . He is tasked with felling the Leviathan , but is sentenced to the death after the sea goddess goes on a rampage around Altissia . He is used as a scapegoat , blamed for the resulting damage in Altissia , and officially sentenced to death ; in reality the new High Commander rebelled against the Empire once their plans for his sister Lunafreya Nox Fleuret were made known . The areas around Niflheim , as well as the capital city Gralea , are enshrouded in a fierce perpetual winter , and the surrounding countryside is an arctic tundra . In M . E . 745 , the military battled the astral Shiva . Her frozen corpse causes a major climactic anomaly , which is in stark contrast to the original surrounding deserts and once lush forests . Niflheim had lost most of its magitek army in the battle against Shiva , and had begun developing magitek soldiers that would be strong enough to fight astrals . Prince Noctis infiltrates Gralea during his quest to reclaim the Crystal , but finds the place devoid of humans and swarming with rogue magitek troops and daemons . When he finds the Crystal in Zegnautus Keep , he is absorbed inside it for ten years , awaiting the day he would return as the True King as spoken of in prophecy . In his death throes as the daemon Foras the Emperor laments his desire to more than just ruling Eos ; by seeking to fell the astrals , the Emperor declared his hope to rule over the heavens and Eos . After Noctis disappears the sun doesn ' t rise again and what is left of the empire collapses , with the world becoming overrun with daemons . Survivors migrate to Lestallum , whose power plant provides the town with light to fend of the daemons . Etymology .
