Before Rudeus found that book on the Teleportation Labyrinth, someone had to write it. This is the story of Animus, a researcher kicked out of Ranoa Academy, and his journey into the infamous Teleportation Labyrinth. Joined by a trio of elves because why not. There wasn't much of an origin story for Animus or the book so I thought I'd write it to satisfy my own curiosity in a weird way.
