From the back of the book:
Legend tells of a wizard so arrogant that he felt the entire sky was naught but a lens for him to view the stars. So great was his hubris and defiance that even when smote with the power of storm and fire, the wizard laughed. He feared not retribution from man nor God, for he drew his knowledge from something greater. Something darker. Something outside.
The legend of this wizard grew, first whispered by men in fear, and later in awe. But then there was no more news. No more talk. Something had finally brought the wizard low, for though the sky still blazed down on him and his abode, he no longer blazed back.
And now you're going to walk right through this wizard's front door.
