One day, Eibon was visited by a demon named Asura. Asura was impressed by Eibon's inventions and magic, and he offered to make Eibon his apprentice. Eibon agreed, and he learned many powerful spells from Asura.
However, Eibon eventually became corrupted by Asura's power. He began to use his magic for evil, and he created many powerful weapons that were used to destroy innocent people.
One day, Eibon was confronted by a group of heroes who were trying to stop him. Eibon fought the heroes, but he was eventually defeated. He was then sealed away in a magical prison, where he remains to this day.
