“The thing could not reasonably be called a blade, or even a zweihänder. It was too big, too thick, too heavy, and much too rough. It was more like a massive chunk of wicked techno-sorcery. Encased by tempered steel, some infernal motor driving a chain of serrated teeth. It wasn’t designed to stab or strike, it was made to cleave, sunder, rip and gore.
Fall where it may, any opponent had no hope of blocking it.”

The Vehement Maw, notes by Sir Gaherion Lamwell.
