The Tractatus de Monstrum, otherwise known as Tractie, is the main protagonist from Labyrinth of Refrain: Coven of Dusk. It is a legendary book that was inscribed by the only person who's ever made it to the bottom of the labyrinth. The player has their soul sealed within the book, thus giving it life-like aspects. Dronya and Luca use the book to explore the labyrinth within the Well of Khalaza.



The book is red with a striped design. Upon obtaining the Player's soul, the book gains a black eye with a yellow eyeball, a crescent shaped in the form of a mouth, a beauty mark and a tail.


The book's personality may vary depending on the player's choices within the game. The book can provide an affirmative response, a negative response or no response.


Prior to the events of the game, the Tractatus de Monstrum was a lifeless book. As noted by Dronya herself, it seemed the tome had only recently gained a soul as she was unable to detect it prior to it's appearance.

The human soul inside the tome was led inside the object by an unknown voice within a book-themed labyrinth. Since the soul's arrival inside the book, it has been tasked with navigating and exploring the labyrinth inside the Well of Khalaza.

Luca notices that the book suddenly gained eyes and a mouth. Upon realizing the presence of the soul within the tome, Dronya used her magic to bind the book to her, forcing it to obey all her commands.
