When it comes to the Underworld, countless rumors and legends abound. So much so that it is difficult to sort fact from fiction. There are tales of lost cities beneath the earth; strange races warped by chaos magic into hideous caricatures of men; and legendary beasts like dragons and demons.
Some of the tamer stories talk of caverns and tunnels in which the laws of nature seem to hold little sway. Some say there are places where time passes differently, if at all!
