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 of his 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.
They 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 Elven Origin stones all around the Tower by creating secret trials for the one who is worthy of wielding them.
It has been millions of years since the man disappeared and gradually the tale about the Origin stones faded into a folktale.
It was not known if the Origin stones had found their owners or not. Where they are? What are their powers? And why did 'That person' Scattered them all around the Tower? Nothing was known.
