The God of Truth and Knowledge, also called the God of Master, was a path that Edward chose for himself. As for the future wizards, just like in the future masters, they would all be believers of the God of Truth and Knowledge.
"There will no longer be blood wizards, dream wizards, element wizards or sector masters!" Edward said.
He then added, "As for blood witchcraft, dream witchcraft, and other forms of witchcraft, they will all become elements of the entire master system. As such, they will be the witchcrafts that people study and conduct research on. They will, from now on, only be the categories of knowledges of different witchcrafts, and there won't be strict definitions like there have been before any longer."
He paused, then concluded, "Everyone will practice witchcraft using the witchcraft book that was bestowed upon us by the God of Truth and Knowledge. In this way, a whole new system will be revealed to everyone in the world!"
