I posted. I made some magical prism cats, called Helkat which are made of ice and are carnivores in icy terrain. As a tribute to you, Helka. It also started the trend in intelligence among species, because these are delineated who hunt in packs of 7. They are crystalline, and each manifests a color of the rainbow, with hue being how you can tell gender. I felt like it would be a little much to also decide how they worked (huning, social order, etc) so I left that up to later. Also didn't do any cosmic laws this time, dice I spent so much time making the Helkats. They're naturally the predators of the reptile herbivores (get it? Ice cats are cold, which sucks the heat out of reptiles, making them easier to catch) and just about anything else.
How far does the ice go? I'm assuming that even though several of us are working on a small scale (one plant, one creature grouping, etc.) That these changes are also manifesting across the realm. So do we have an ice world at the moment?
