Origin Stones
There was a story among the people of the Tower that the one who created the Tower was a powerful person who could destroy worlds on a whim and create miracles at will. It was said that he was a being who overcame time, space, and death. He was pictured as a man with eleven stones hovering around him.
Those eleven stones emitting ethereal energy were called the Eleven Origin Stones.
What happened to that man or where he was, nothing about him was ever known to the people, but what they knew was that that person scattered the Eleven Origin Stones all around the Tower by creating secret trials for the one who is worthy of wielding them.
It had been millions of years since the man disappeared, and gradually, the tale about the Origin Stones faded into a folktale.
