But as the narrative goes on, Magnus discovers secrets about the place he is living in and how he ends up being attached to the Astral Realm. Magnus's past life haunts him, presenting challenges that transcend the typical hero's journey. And everything changes when he returns to his original body. It is not like your typical reincarnation.
