In the steaming depths of Sub-Basement Three, twenty feet beneath the central lattice cage, Pella Rook and Varo Nenn knelt beside the witness return water chute. everyone could feel the sulfur fog and thirty-eight degrees of humid heat, the granite floor shaking with the rhythmic thump of the bubbling blast pulses.
There, underwater beneath four inches of boiling river foam at the mouth of the return under-road drain, lay the end-post spirit hardware: an ancient, four-flanged collar of cast bell-bronze bolted directly to the bedrock. Coiled around that bronze collar was a fine, detailed, pulsing knot of cobalt-blue light. The ‘name knot,’ the final spirit anchor through which Master Davin Sorell had bound Senn’s core essence to the Sluice Crown.
‘Here is the secret shackle,’ Varo Nenn whispered, pointing with his brass metal pen. ‘This is where Sorell pulled out the spirit’s true name. The ancient word for the Gray Rush before the First Archon built the stone dikes. As long as this knot is held in this bronze clamp, the spirit can’t withdraw into the riverbeds. It must turn the turbines until its essence dissolves into raw steam.’
Pella lowered Ada’s tone check rod into the water. Through the copper earphones came the sound of a voice. Not words, but a deep, mournful deep ring that sounded like water grinding over rounded boulders in an ancient canyon. The spirit was not pleading for worship. It was asking for an honorable end to an impossible task.
