Burnstorm

A deadly, supernatural storm that occasionally besets Vaskeer. The storm originates from the Burn itself and is fuelled by the power of souls, many of which are flung about in the midst of the storm and strike the ground. Storm Hunters seek these Burnstorms.
There are any theories as to why these Burnstorms occur. The most prevelant idea in modern day is led by Arthumar Glore .
The First Burnstorm occured exactly 100 years after the raising of the Ivory Wall according to historic records, which has led Arthumar to believe that they are related. Now, on the first day of every new century, the worst Burnstorm appears, progressively worse than the last. Burnstorms now occur frequently, but they are dwarfed by their centennial counterparts.
