DarkBlood -Gaiden-

At the end of the world, there was a tower towering above the sky. It is said that the tower is filled with treasures that fulfill people's wishes, attracting many adventurers, but none of them have returned. Then, the tower came to be called "the tower that never returned". Therefore, the King placed the unreturned tower under his jurisdiction and arranged a knight order to investigate the inside of the tower.
