From publisher blurb:
For 3-4 Level 20 Characters
Tempest Tower is a spire that reaches skyward from an expanse of open plains. The stone monument rises nearly 100-feet above mostly-featureless terrain. At its apex swirls a maelstrom of storm clouds that extend half-a-mile from the center. The landscape directly below is speckled with small craters and charred vegetation from frequent lightning strikes. The sound of rolling thunder is near constant and can be heard for miles in every direction.
The tower was constructed eons past to bind a powerful monstrosity from the elemental plain of air known as the Storm Song which once roamed across these lands, consuming the greenery and the earth in which it was rooted – creating the vast, featureless plains that now exists.
