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 moonlight & silver, the Crystal-Horned Mosaic Unicorn was observed near the Illuminated Memory of the Last Scribe, though its true habitat may lie in dimensions the medieval mind had no geometry to describe. It has been faithfully preserved in mosaic tessellation, though the original scribe is said to have wept upon completing it.
