This heraldic unicorn basilisk was catalogued by an unknown illuminator whose marginalia suggest they considered it the most dangerous specimen in the bestiary — not because of venom or claw, but because of the ideas it implants in those who study it too closely. It radiates ruby & blood and has been sighted near the Archive of the Self-Writing Codex. The heraldic blazon rendering preserves something the original scribe could only gesture toward.
