Since ancient times, there has been a dark secret kept by the royals of Lucis, keepers of the crystal; that their world, Eos, is not alone. Over millennia there'd been many visitors to the lands of Eos, though those visits were brief and discreet. The public did not know of other worlds besides Eos.
Until ten years ago, when the world of Thaos and its largest kingdom, Ikkaros, made permanent contact with the Kingdom of Lucis, offering goods in exchange for materials harvested from Lucian soil. It was because of them that Lucis had the supplies necessary to keep the empire of Niflheim at bay as they encroached on the crown city and its crystal.
But little did they know, Ikkaros had schemes of its own.
It all began with an offer of the hand of their princess, the fifth in line, as a way of bonding their nations and a promise to keep the empire at bay, but there was an ulterior motive. They needed to rid themselves of a troublesome princess, and they knew how to keep her silent.
Regis has his own suspicions of the mysterious kingdom's motives, and thus, with his son already promised to Lunafreya, he chose Noctis's royal advisor in his place to keep an eye out for anything suspicious with the princess.
