From Creatures Wikia
The Camelot Norns were created by Nimue. They are available for Creatures 2 only and occupy Ettin slot F. They use the Golden Desert Norn genome and represent the element earth. They are born almost completely green (to allow them to hide in the undergrowth) but their hands, feet and bellies gradually turn blue as they age. Throughout their lives, they can be identified by their large glittery tails. They are close relatives to the Morrigan's Lake Norns.
The Camelot Norns can be found at Creatures of Avalon.
