Really cool Justin! That is one thing I never did was RPG maps. The bottom looks like it would host a whole range of nasty beasts.
Thank you. Just one, really big one. The tunnels are all dug into solid ice. The beast is the spider-legged dragon-thing in one of the images. He melts tunnels in the ice with his breath and it freezes again almost instantly. He's called the Hellfrost beast.
