    Bronze-worms...deadly poisonous. They burrow right through your skin & into the bloodstream. Due to their small size & molecular similarity to haemoglobin, they cross the blood-brain barrier and cause addiction to metal-working, especially with copper-tin alloys, thus ensuring their continued reproduction.
