They probably also owned the Five Elemental Overcoming which they used to the change the magic system of the world and thus introduce it in the New World as magic accessible even by humans. It was later spread into global prominence by the 8GK. The issue of it being corruptive of other magic (like Wild Magic and Runecraft) is probably related to that change in the laws of the world regarding magic overpowering already existing laws on magic. It doesn't exactly affect Talents and Martial Arts though as they are probably more about (individual) traits and skills.

Though I can't exactly explain why it also lets people create new magic that's probably within the Tier Magic system as well, like Evileye's [Vermin Bane] and Fluder's 6th tier [Obey].
