Greystrom

Greystrom or Blight clouds are a weather phenomenon that occurs down wind of Ashed cities focused on manufacturing of refined products such as heavy metals, treated woods, glass, or other products that produce heavy toxic smoke that mingles with clouds causing an acidic rainfall.
These storms often blow from the Midlands to the Firelands often moving into Goran territory, causing massive swaths of dead vegetation, injury, and structural damage. These storms are thought by the Goran people to be constructs of pure malice created by the Ash born to blight their lands, and are often the reason for Goran incursions into Ashed land.
