A wandering Magi. Magi's were known as world creating sorcerers, they are called "children of Rukh's" for they have the ability and power to control Rukh's unlimitedly. Magi's are the ones who choose the "king" and Magi's are the one who will guide and teach the king they chose

However, there are also Magi's who are unaware of their existence. Worse, there are Magi's who do everything for fun and war. For example: Judar

Back then he was basically a huge ball of power. All he does was wander around aimlessly and fight, kill, battle. Judar found peace and interest in wars. Though that was until he met Eros. Eros is the first prince of Kou Empire, the current largest country

The two of them first met in battle, both of them fought each other. And surprisingly, that was the first time Judar ever felt such excitement and joy. Although of course, A magi is a magi. And a human is JUST a human. In the end Judar won, although he didn't kill Eros. Eros still suffered a heavy injury on his right eye which left a permanent scar

After that, Judar aimlessly surrendered despite winning the duel. Although humiliating, Eros didn't even bat an eye nor reacted as he arrested Judar. Since then, the two would often clash swords for practice. Judar was doubted at first but when his and Eros's friendship stayed he was soon recognized as a real Magi. He was titled as the Lord priest of Kou Empire

And as time passed, Judar completely became attached to Eros. He did try everything he can to remove Eros's scar using his magic but failed each time. Though by now Eros doesn't even care nor hold a grudge against him, they remained friends. Close friends. Perhaps, even now. Eros is the only one who Judar obeys and listens to. Even though he complains and acts shameless all the time, deep down he does listen

For Eros is the only reason he's Siding with the Kou Empire anyways
