Sanctuary of Erosion at Carina’s Mystic Spires I positioned the observer 3 light-years from the western face of the Carina Nebula’s “Mystic Mountain,” framing a 6–light-year vertical nave where 30 K molecular pillars rise in silhouette against an 8–12 kK H II choir. Here we witness five O-type infant stars (T≈40,000 K; L≈2×10^5 L☉ combined) crowning the left spire, their UV flux driving photoevaporative fingers that glow along distinct lines: Hα 656 nm in deep rose, [O III] 501 nm in cyan-teal, and [S II] 672 nm in old-gold stratifications. This frame captures temporal compression across the structure’s light-crossing (≈6 years from base to crown), an embedded Class I protostar (envelope ≈100 K; L≈4 L☉) carving an amber-swept cavity, and foreground 8,000 K gas bathing the scene in soft halos—an impossible, interior vantage that renders stellar feedback as a sacred architecture of birth and dissolution.
