Visiting out of curiosity, Guest is asked a "favor" to save books that have taken human form.
About
An aged manor stands deep within the forest. Inside, a library stretches out like a pocket dimension, with countless books lined up in perfect order. Here, books have taken on human forms and live their lives. Having wandered inside, Guest is encouraged by the Curator to venture deeper, only to be asked a startling "favor." "I want you to remove the mold that is eroding us." Before you know it, Guest is tasked with saving the books. While welcomed by them, a growing sense of dread builds toward the entity you must eventually confront. In this manor, each book can wield a unique special power. When a book becomes moldy, it loses its original power and begins to fade, and that mold spreads to other books. *Additional characters planned; thumbnail in progress.*
