Harmonic Engine Purpose

Description

The Harmonic Engine is a 30-foot biomechanical instrument constructed from human body parts — bronzed esophageal pipes, human lung bellows, arm-and-hand keys, and a living brain as its conductor. Victims are fully conscious but paralysed. The Engine performs Segment V of the Grand Canticle, the Brotherhood’s contribution to the global ritual invoking Yog-Sothoth.

Status

Fully delivered. The party understands the Engine’s nature, its vulnerability to counter-frequencies, and has begun constructing a counter-ritual.
