Superbia

The God of Artifacts, and the one whom King Arthur trusted, was the creator of the three strongest artifacts: the legacy, the crown, and the Isotox. All these three held unimaginable powers that defied common sense. 

It could be argued that the holy crown, which appeared every thirty years with more challengers than ever, was stronger than the legacy. However, if the powers of creation were considered, there was no telling which. Arthur received a fraction of that crown's powers, known as Insignias.

A notification appeared as Arthur tried using his insignia to undo the astral venom, but it got rejected. The first time this happened, Arthur fought against Jasmine, his sister. After that, he tried it on several instances, like disabling his mother's comatose state, but it was the same.
