—20 years ago, the Gates of Underworld opened around the globe causing the Demons to breakthrough our Realm. These monsters slauthered humans like pigs, light up the cities on fire, and claim the human territories for themselves. They killed anyone they saw: man, woman, even childrens can't escape they're wrath.
After many years, the human population dropped severely as well as human territories. But humans learned something that will change everything—Magecraft. With this Humanity got a chance to defend themselves from the Demons they now have a way to hold the fort.
The remaining humans decided to build an Empire, collecting the remaining population and territories they managed to build the Last Civilization, the Last Humanity Stronghold—Kingdom of Babel. By the help of Magecraft, Humanity retrieve plenty of Human Territories spanning 7.462m km² and defended the frontlines till this day forward.
