Circulatory Norn

The Circulatory Norns (also known as the Lymph Norns) are a genetic breed of norn for Creatures 2 that have actual blood in them. They were made by Andrew Carroll and used to be at his site, Close Encounters of the Creatures Kind, but are now only available at Albia: Home of the Norn. They were followed by the Immune Norns for Creatures 3.

Originally, Creatures didn't have real blood, or the representation of it that would cause blood-related illnesses or transmission of chemicals in the norn's biochemistry.
