From the Back Cover:
The Legend - Loose upon the winds of the tempest, astride his fierce steed, is a rider, a creature of rage, a creature of the storm. It is said you can see him dancing over the gray clouds, urging the winds onward to greater ferocity. When his anger is especially fierce, he descends to the earth to wreck havoc upon the good folk, leaving only his flaming hoofprints behind. Some say he was a man whose passion overcame him, and who now looses his rage upon the winds of the storm. The magus Grimgroth insists he is an elemental, a magical incarnation of the air. Others say he is a foul demon, a Horseman of the Apocalypse, sent to earth to torment the good folk of the valley. However, all of them know him as...The Stormrider.
