The Osiris Norns were one of the first genetic C3 breeds, it was the first kind of "expressive" norn genome, predating Creatures Labs' own expressive genome. They were capable Ettin and Grendel hunters, and were used to help control overpopulation. Due to the nasty habit they had of killing ettins for no reason the download was taken down. An offshoot of Project Osiris were the Set Norns.
