Great Weather Machine
The Great Weather Machine was a magical device developed by the Crone Hegemony. As the Crones were driven out of Ilmari by The Council of Thirteen, they destroyed the machine. Ilmari was covered in storms for the next 24 years, transforming the fertile landscape into a barren desert.
Rumors of the Great Weather Machine appear every so often, with some believing it remains intact somewhere under the Ilmari Desert. The Naturesphere may operate on a similar magical principle to the Great Weather Machine.
