Vrai nanite weapon

The Vrai nanite weapon is a weapon developed by the Vrai. The nanites were originally capable of eating any material except protosteel, due to the fact that Vrai body armour is made from it. Barricade stole a vial filled with them and modified them to eat protosteel. He later unleashed them on Hokagetsu during the Battle of Darkmount. They didn't work very well.
