A dangerous, alien plane where glowing frog-slimes slither and slurp, metal-skinned bird people rebuff diplomacy, and only the endless subterranean tunnels are safe (just mind the gravity-bending moles). Visitors will have to skulk around in the dark to avoid the curse carried by the sunlight. Because (have I mentioned?) the sun is the source of a powerful curse--one that covers the whole planet.
The frozen wastes stretch for miles around. Something waddles through the snow. It's a penguin: An emperor penguin. It waddles slowly, meandering toward the sea. The ranger freezes. "Stay very still," he warns. "Don't move at all." "What is it?" I ask, breathlessly. "It's the most dangerous creature in the whole Yahoo Tundra, and that penguin's about to kick its butt..." (Sorry, Epi! I couldn't resist!)
