Eye of the Storm

From opening paragraphs: The storm detailed below is both a chaotic environment where air elementals and air-aligned creatures have taken up residence, and a fortified sanctuary for an NPC known as the Lord of the Storm. The Storm itself is a vast thunderhead that rises 12 miles high and stretches 30 miles long. The air itself quivers and vibrates in the presence of the storm; thunderclaps fill the air and lighting flickers and flashes within the cloud.
