Description: An instruction manual for the design, repair, and general use of robots. Most of it contains complex equations and intricate designs beyond the understanding of an average person. At least the scribbled notes in the sidelines may provide an idea of the book's contents.

Lore: This book is unavailable in the majority of bookstores, for the simple reason that almost no one can understand it. It claims to be the most accurate and detailed guide on all manner of automatons, but no one can confirm nor refute this claim. Even dedicated researchers find this hard to understand, and their thoughts on it are inconclusive. On one hand, the blueprints and calculations within are detailed, accurate, and match what is known about the Ruin Guards. On the other, some of the claims that it makes are simply unprovable, for no one can manage to study an automaton in such depth.
