From Creatures Wikia
The Jewel Norns were developed by Lisa of The Mystical Forests of Albia for Creatures. The sprites were based on those of the Wood Norns, while the genome from Neogecko was customised to create some differences... They occupy norn breed slot 9, clashing with Lis Morris's Grorns, and the Ettorns.
The Jewel Norns can be downloadet from NornenMeisters website.
