Soran Xenthos completely sucks at being normal. Being found inside a destroyed mech in the middle of a civil war in the year 3981 certainly made him unique. He has also been able to manipulate fire before he could even learn how to walk. On the very long list of the things that make him special, the one thing he truly hated was the strange nightmare that he can't seem to get rid of. A night of horror and death involving a woman named Alara and a man named Solomon who ironically looks just like him.

Now living on the fourth planet of the Prime System known as Neo Arcadia, he attends the Albion Military Academy. A special school comprised of students from each of the Prime System's six worlds. Though for the past two weeks he's spent time in suspension for an altercation at school gone horribly wrong. For his first day back he hoped he could spend it peacefully with his friends, Andrew, Clarke, and Talia as well as his cousin Minerva. Yet he found his hopes dashed away as a school rival nearly kills him.

Moments before death, Soran comes face to face with Solomon himself, who reveals that Soran is actually a member of a long-forgotten race known as the Arcadians. Beings made of living Ether, the unlimited energy source that powers the very society Soran has known. It is then he gains awareness of his true potential as the holder of an Arcadian Marker called "The Fool."

Realizing his destiny, Soran is entrusted by Solomon with the task of stopping Lucian, the man who murdered Solomon eons ago from realizing his ambition of creating a utopia, where only Arcadians exist. However, Lucian's cunning knows no bounds as he attacks Albion Academy in an attempt to recruit Soran for his grand ambition just after the latter awakens to his true self.

With the Prime Council and Solomon now placing their faith in Soran, he must acquire the secrets hidden within the Fool that will lead him to Lucian's ultimate goal. The Arcanum Astra, a device that is said to have the power to shape the very cosmos itself.

For that he will lead the greatest fighting force the Prime System has ever created... Nova Astra.
