Sound-wave tower defense: bell towers emit expanding concentric rings that damage on passage. Overlapping resonance zones multiply damage; choir swells grow louder with chains. Signature: align three bell rings on one node for a chord strike.
Ivory and gold on deep midnight blue, visible ripple rings, cathedral silhouettes, dust motes in candlelight.
