The Inhuman Emperor's Divinity was far simpler than Damien's.
Its name was "Blissful Agony."
It did not refer to finding bliss in a state of agony, but rather, in line with his character, represented the bliss he felt forcing other people to endure agony.
The attacks he used were more akin to torture than killing techniques, and the laws he used had been convoluted to the point where they weren't necessarily laws anymore.
His Demonic Providence, Executioner, also backed his Divinity extremely well.
Using a combination of Blood Laws, Metal Laws, Illusion Laws, and several others, he created a power that was hard to explain as just magic.
When the Inhuman Emperor heard of Damien for the first time, his thought was just as simple as every other thought he'd ever had.
Such a talented human was a perfect subject. Someone who could hold the weight of the universe's hope on his shoulders…how blissful would it be to see him suffer?
