According to these scrolls, something big happened, an event that was called: The Fall.
He didn't find any reference for this world's name, so he decided to call it The Origin. As for what exactly happened back then, the scrolls didn't give any useful intel.
Yet he was surprised to learn that the Mystic Arts original world, the one he called before The God Realm, was connected to the Origin world alongside the Spirit world as well.
According to these scrolls, there was a fixed and known path for contacting and getting in touch with these two worlds, not to mention a well-known method to rise up and ascend to higher realms. Yet all this seemed to get lost when the Origin world got damaged, broken into such a messy collection of tiny and outer worlds.
That wasn't all. William knew the right way to go up from one tiny world to the outer world was already missed and lost for those living in these worlds.
