of course! I'm yet to make a trait sheet, but I should tell you
-the rib cage can have spikes and can have as many ribs as you want
-wings/extra limbs are allowed
-you can give it horns
-the spirit lava (which I'll explain later) is mandatory, but it can actually be anywhere and you can have as much of it as you'd like/any color, but it's always flowing upwards
-the tail length can be whatever
-it can have scales, fur, or both
-hybrids are fine if you wanna do that
feel free to get creative!! can't wait to see what you make. Anything I didn't specify is free range, so mess with it as you'd like, have fun!
