Prism Patrol

A blinding spark of sapphire and crimson flashed across the hardwood like an evasive abyssal dartfish! Dropping into an agile crouch behind the curtains, I tracked the flickering spectrum straight to a heavy glass prism resting on the lower sill. Instinct took over! I charged forward and planted the golden prong of my right trident dead against the cut crystal bevel. The beam fractured instantly! A brilliant cascade of rainbow scales sprayed across my breastplate and lit up the floor like an illuminated coral trench. I held the strike steady, marveling as the vivid bands flared and danced with every tiny tilt of my wrist!
