When Malin entered this world, he wasn't surprised to find that he had become his former self: on one hand, an Earth monkey past middle age, and on the other, encased in the flesh foundation of the Silver Folk. The two were utterly incomparable.
However, Malin had no other choice.
If he gave up, not to mention his foster father, those two Divine Masters, Malin might as well find a crooked tree and tie himself to it organically with a rope.
Therefore, he had to find his sister and then take her away.
But Malin had never imagined things would turn out the way they now had. As he reached out to take his own skull, he sighed sorrowfully at the sight of his sister who had completed her transformation—this Maya knew all too well that no bride would tolerate witnessing the remains of her beloved being desecrated, so in her final moments, she tossed Lorrin's skull to him to prevent herself from being distracted.
