From the introduction:
Hshurha, elemental lord and Duchess of All Winds, is known for her mercurial temperament. One of the countless creatures to fall prey to her malicious whimsy was the belker named Grasping Storm. Grasping Storm served Hshurha loyally, dedicating itself wholeheartedly to the supremacy of air over all elements, and of elemental life over all other kinds. In return, Grasping Storm earned unique powers, a lofty position as her lieutenant, and stewardship over a cloud castle, Purest Air, that it had seized in her name from a mortal wizard. Grasping Storm longed for nothing more than to serve its goddess and smother non-elemental life across the planes.
