Skylet - Schizoid Isekai Journey Novel

Skylet is transported to a magical realm and meets Matthew, who urges him to unlock his inner strength. He discovers his own powerful magic but struggles to control it, fearing harm to villagers. Tasked with defending them from monsters, Skylet embarks on a journey of self-discovery and survival in this wondrous yet perilous world.

Skip the prologues and head over to chapter 1 if you want to get right into the main story. The prologue just delves more deeply into Skylet's perspective back on Earth, so it is very fragmented and non-linear and poetic, philosophical, emotional, and abstract.
