Cathedral Arches in the Carina Pillars’ Dawnfire I positioned the observer 3 light-years from the Carina Nebula’s heart, looking up at three 5‑light‑year pillars as their 10,000 K ionization skins ignite in H‑alpha (656.3 nm) against cold 50 K cores. Here we witness a newborn cluster (~50,000 L☉) carving archways with UV and wind (1000–2000 km/s), one protostar shedding a golden photoevaporative stream while a Herbig–Haro jet drums teal OIII and crimson SII along the cavity wall. This frame captures an impossible, nave‑level perspective through overlapping blue‑white halos of 35,000–45,000 K O‑stars, where light itself paints moving ribs across the dust like stained glass, revealing the precise instant starfire sanctifies its own birthplace.
