It is the year 1461 in the wondrous world known as Valerion, where humans have prospered greatly in the use of magical forces and early science due to the recent discovery of a valuable magical metal known as Ruthium. Because of this, almost seemingly overnight, society has transformed in to one reliant on its uses in just about everything. The Baldune Continent's utmost superpower, the kingdom of Euxaria, has managed to stay at the forefront of this magical and technological revolution for a while, making way for continued peace between the six kingdoms thanks to its noble and just monarch, King Darius II. But although most of the kingdom has been kept happy and thriving, there is the exception of the Barbarian Legion, which continues to attack the out-land cities surrounding Euxaria. Because of this, King Darius has had to shift priorities over to dealing with these criminals, while in the meantime raising his own son, Zahe Kuroi, to be the kingdom's next heir. However, Zahe does not care about his father's wishes for him to succeed the throne. Most of the time, Zahe would prefer to tinker with his machines, read novels, or study philosophy and magic rather than listen to his father go on about the responsibilities he'll have as the future king of Euxaria. He has his own way of doing things which are not of tradition, but instead based off of what stays true to his own beliefs. Unfortunately, with the kingdom's people being very comfortable with and protective about their ways of living, this has not earned him many favors. Instead, his people scorn him and express distrust of what his intentions will be when it is time for him to inherit the throne.
As tensions rise to a boiling point between his kingdom and the Barbarian Legion, King Darius finally decides to negotiate a peace treaty with the barbarians in an effort to quell the storm rising between the two opposing factions. The treaty is initially accepted by the barbarians, but when a surprise attack is orchestrated on the castle by a legion warrior named Gorgen, the castle and its inhabitants are thrown in to a state of disarray and pandemonium the likes of which haven't been seen for over 100 years. While Zahe struggles to search for his father amidst the chaos, he meets a young traveller by the name of Gerard who was separated from his friend during a raid on the city markets. Together, they combine their efforts and continue to search while finding out that there is much more to the attack than what meets the eye, and much more at stake than just the Euxarian kingdom.
