The first person Wang Wei thought of was one of the Six Cardinals — the Magistrate of Heaven. From Wu Hong's notebooks, he learned the basic names of these six individuals, and Wang Wei believed if there were someone with the strength, knowledge, and possible motive to scheme against him across space and time, it would be him.
However, Wang Wei had his reservation about this deduction for a few reasons. The inheritance does not seem to come from someone who created True Heavenly Dao but from someone who knows a great deal about it after years of research. Secondly, the fact that the inheritance only went as far as the fifth reincarnation and encouraged its owner to travel to a non-primary Source Chaos World was a sign that someone with limited power or ability did it.
