The continent of Xipoli, a land full of mystery and riches.500 years ago, 10 brave knights stepped up to face off against the Demon King, who would have otherwise brought ruin to Xipoli.After 15 days of fighting, the Demon King was finally slain inside of his own palace.Right before his death, the Demon King cursed the entire continent: all children born from that moment onward would only be male, and there would be no females.If that continued on, without the birth of female children, humanity would be doomed to a slow extinction.To reward humanity for their bravery and sacrifice, the Elves sang hymns under the Tree of Life, but were unable to break the curse in the end.As a stopgap solution, the elves implanted their "egg" into humanity's collective vein, so that all future born humans would possess an egg of elf, and a new law was made for the continent.With swords and sorceries, elvenkind and humankind live and work together to survive on this world.
