The life of John Casterdyne has recently taken a set of bad turns; he failed his college subjects, he got to spend his vacation attending summer classes, and he got dumped by his girlfriend. With a talentless loser like him driving his own story out of the rails, he got stuck in a suicidal depression. As a matter of fact, this dolt will attempt to drown himself in a small lake!
On his way to kill himself, he encountered a wounded woman in a grove that will change everything. Nursing her, John was offered a contract which removes him from his sloppy normal life and has the lucky chance to learn about the world's mystics, to gain a power that only kings of legendary kingdoms possess: The Archonlight System.
He soon learns that the sassy and cold woman he saved is the Princess Alessia Erindel of Agartha, who is now wanted by her own kingdom for allegedly killing her own father. She claims that she was framed, but John believing her wouldn't change a thing. It would even make his life shittier.
This is the genesis of the greatest Archon that ever exists.
