More time passed.
15,000 years after Mortis got together with Azure, Gravis managed to finish the Law of Stone. It had taken longer than expected since he didn't have Mortis' help during all of this.
Mortis was spending nearly all of his time with Azure, which was a good thing in Gravis' mind. Gravis knew how it felt to be in love, and he wasn't angry with Mortis. After all, Gravis had also spent a lot of time with Stella back then while Mortis was comprehending more Laws.
This was the first time that Mortis didn't focus on power, which showed that Mortis finally had found something that he found more important.
Mortis finally found happiness.
From what it looked like, Azure and Mortis were a perfect couple, and they were constantly with each other.
