A maze of steel and crystal blades summons demons and bladehounds from this world and worlds beyond. Seven huge boulders float a mile above the earth—legend says they guard against enemies among the stars, and indeed cruel, stone-armored creatures do fall randomly from the sky in this area. A massive ribcage rises from the earth, a giant weathered skull resting nearby. Creatures in the area—from simple insects to terrifying abhumans—grow to monstrous proportions. Explore eight detailed sites as adventures in their own right, or use their rich and intriguing settings for your own quests. Each contains a vertice to the datasphere, unlocking that strange realm and creating a teleportation network for quick—but always interesting!—travel across the Ninth World.
