Diesel Resonance Plumber

The unwashed saints who keep the bastions from collapsing — and are blamed when they do.

The Diesel Resonance Plumber — Pipe-Singer, Thumper-Runner, Heretic Wrencher — maintains the pressurised diesel conduits that carry resonant vibration through the bastions' bones. The Bureau of Engines insists this work is impossible. The bastions continue to require it.
