The Law that Dorian had studied, to some basic level, was the Law of Wrath. One of the Seven Great Laws of the Demon Race, and a powerful Law that could empower attacks, among other things.
It was a Law that had been discovered many years ago, one that was once well known when Demons walked the 30,000 Worlds in their multitudes. While it had fallen to the wayside now, and was a Law few would recognize, it was still a strong Law.
When Dorian had rejected Yukeli, something had changed.
For the first time, Dorian had firmly thrown himself off the path that Yukeli had prepared for him. Dorian had chosen to walk his own way, instead of giving up his consciousness and life to merge with Yukeli.
While Yukeli's goals and dreams were huge, and the man had achieved incredible success in his life so far, they did not match up with who Dorian was.
