Crystal Entity in a Steampunk Engine Core

A radiant crystal entity suspended within the humming guts of an antique steam engine. The entity is a multifaceted translucent crystal floating above brass gears, pistons, and riveted plates, its facets catching and refracting the boiler’s glow. Steam wisps curl around the chamber as copper pipes and pressure gauges loom in the background. The crystal emits a cool cyan and magenta glow and is surrounded by orbiting digital glyphs and particle dust, giving a fusion of steampunk and cyberpunk aesthetics. The engine room is rendered in hyper-detailed digital art with cinematic lighting, warm brass, polished metal reflections, smoky atmosphere, and a dramatic depth of field. The crystal acts as the heart powering the machine, a living, sentient core in a steam-powered world.
