It's not clear if the two travelers in this concept art have crashed into this glowing cavern, or if that's simply their parking place. Maybe there's a swarm of flesh-peeling mites just out of view, but it looks like a good place for an adventure to us.
French artist Mathias Verhasselt works as a concept artist at Blizzard Entertainment in Irvine California, although his art tends to lean more towards science fiction than it does World of Warcraft. Maybe he's working on some of the designs for the much anticipated Starcraft 2. If you want see a lot more (and we mean a lot more) of his designs, check out his website, which is basically one giant gallery of images so be warned when you click on the link. He's tossed everything from steampunk tankbots to alien species in there, and most of it is very impressive.
