If anyone missed it – the “Atlantis” Riser has a “Production Note” as part of his description:
“PRODUCTION NOTE: We will likely be making Limited Production dragons in a color similar to this in the future!
Dragons in a very similar color scheme will most likely be available in our store at some point. The color scheme WILL differ slightly from these Atlantis test paints. For instance, the Limited Production version of this color is planned to have gold detailing instead of copper, won’t have copper colored horns, may have less copper on the wings, and may have less detailing in general to make them faster to paint.”
