Horcruxes Were Only Anchors

"After all, I only learned about it from books. I never truly understood it."

To be honest, by this point Manus had already mentally discounted the reliability of the Wizarding World's books. Even some magical knowledge had omissions in terms of accuracy, completeness, and other aspects.

But while using Big and Little Tom's memories for experiments some time ago, Manus had learned from the many Dark Magic books Slytherin had left in the Chamber of Secrets that the difference between a Horcrux and a Horcrux was even greater than he had imagined—
