It's pretty cool. Was just reading D&D's Frostburn, a genre book about ice wastes (natural, magical, or extraplanar), and this terrain makes me think about that. I forget what it's called but there's some sort of blood ice in there...along with negative energy ice and other nasty stuff. I remember reading about a few of them and thinking, "that's kinda lame". But, now that I've seen red ice, maybe I'll have to change my mind.
