The Tormentors
From Solium Infernum Wiki
Description
I presume their success comes from individual strength because it is not for cohesive fighting that others fear them. I have never seen them in combat--in fact, most who retain the ability to speak and write can only claim likewise--but I can deduce that seclusion, guile, and supernatural strength align to their side. It is as if each were gifted with semi-fiendish powers, which now make them stand a hands-width above the rest. --From an uncompiled source of notes by Bishop Bezel
