The Next Morning
-----
When I woke up, it seemed that several hours have passed. I ended oversleeping because I talked a lot with Tyr, which I asked many questions. He had his memories lost, but whatever remained of his common knowledge was amazing. Although that was all of it, he didn't really knew more than that. If I want him to regain more memories, I should find more of his fragments and eat them. That'll slowly unify his will from each fragment, and it might also help me grow stronger as well… Hopefully.
He also said I still have to evolve a couple times before I could even grasp the concept of being a demi-spirit, whatever that truly means. I guess to grow stronger and surpass what a mortal is capable of, a person must become this sort of "demi-spirit" by channeling their elemental aptitudes and "merging" them with the world around them. Similarly to how gods are capable of representing an element, and the spirits being the pillars and materializations of such elements.
