The Fireclaw Heart is a rare, glowing organ harvested from the formidable Fireclaw machines, resembling a fusion of biological and mechanical components. It features a central core of pulsating, orange-red energy encased in a metallic, rib-like cage with intricate circuitry patterns. The surface is smooth yet slightly uneven, with visible seams where organic tissue meets synthetic materials, emitting a faint heat haze and occasional sparks. The heart's glow intensifies when handled, suggesting its volatile nature.
