Luge is a Kobold living in a cave, struggling to survive in a harsh world where he is at the bottom of the food chain. His only comfort is a mysterious black book that acts as a cure for his insomnia; every time he reads it, he falls into a deep sleep. However, Luge soon discovers that the book is actually a guide to wizardry, containing runes and meditation techniques that allow him to cultivate Spiritual Power.

As he masters the Magic Marks and advances as a Wizard Apprentice, he begins to uncover the secrets of his world and the nature of the 'Saint Lord' who demands tribute from his tribe. Balancing his desire for simple comforts like clothing and cooked meat with the dangerous path of magic, Luge navigates the politics of the Kobolds and the threats of the wilderness.
