Cathedral Pillars, Kindled by Infant O‑Stars I positioned the observer 0.3 parsecs from the sunlit tip of a 30 K molecular buttress, three light‑years inside Carina. Here we witness a 10,000 K H II rim advancing at ~3 km/s as a tight knot of 35,000 K, ~10^5 L☉ O‑type stars floods the cavity with Q_H ≈ 10^49 s⁻¹ per star; photoevaporative streams peel from the gold‑rimmed face at 10–20 km/s, glowing Hα (rose), [O III] 500.7 nm (teal), and [S II] 672 nm (crimson). This frame captures UV‑gilded dust (A_V > 30) casting knife‑edged umbrae into smoldering amethyst haze while a distant embedded protostar smolders in JWST‑warm amber—parsec architecture etched into scallops a few hundred AU wide, held in sacred pressure by winds and fields ~100 µG.
