My idea is that there there 2 brothers, one of them a genius inventor, the other one, a complete neanderthal who loved making up tall stories and playing tricks on people. The Inventor made a machine he jokingly referred to as "The Trash Bin" that taps into a dimensional space, specifically for the utility of "getting rid of all the things that society will not accept in this world". The Inventor, somewhat spiteful, decided to extend this sentiment towards his brother, and quietly had him removed so that he could, for the first time in his life, have a Peace of Mind.

Alas, the Neanderthal did not die, but he did feel greatly saddened about his brother not wanting him in the world where he was.

The Neanderthal was eventually joined by others just like him, those rejected by society. They started a Kingdom, and it was one that had surprisingly become a HUGE and Prosperous community of one great, happy family that had a deep and intimate concern for one another. As for the Neanderthal who became King and united the rejects, He attained an incredible love for his new friends, his new family who he swore to never stop protecting, and also attained an incredible power. His strength, love, and newfound knowledge, all these became the basis for his willingness to never yield to the enemies who threaten the happiness of his Kingdom and family.
