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 ruby & blood, the Luminescent Wyvern-Hydra Hybrid was observed near the Codex Aureus of Canterbury, 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.
