From publisher blurb:
Even in the far gulfs of space, the struggle of Law against Chaos, Good versus Evil is eternal. But wherever evil is not extinguished, it will revive to exact vengeance on those who would keep it at bay...
...On the fringes of the realm, where civilization wanes and adventures begin, rumors are whispered of a castle that fell from the sky. Some say it has poisoned the land where it fell and nought but death can be within its walls. Some say creatures, foul and dangerous, have gathered at the dark fortress. But others, the treasure seekers and thieves who haunt the local taverns, scoff at such dire warnings and view them only as a thin ploy to keep adventurers from winning the vast treasure that surely waits within. To your ears have come these very rumors— and more: you have learned the location of the fallen sky-castle!
