The learned monks who catalogued this specimen insisted it appeared only during liminal hours, when the boundary between codex and creation grew thin. Composed of prism & chromatic, the Auroraborealis Sky Wyrm was observed near the Crypt of the Autonomous Scribes, though its true habitat may lie in dimensions the medieval mind had no geometry to describe. It has been faithfully preserved in crystalline refraction, though the original scribe is said to have wept upon completing it.
