Much like the Empty Child plague, the term can be thrown around two ways: a symbolic meaning and a straight definition. For the Empty Child, a child who acts hollow and empty, and a plague associated with the nanogenes that twisted his appearance. For the Crimson Horror, the nickname of the red leech, and the phenomenon pertaining to the red-skinned victims of its venom.
