"Correct! Now that’s the simplistic version. Magic in the Material plane is like water filling dry dirt. Magic filling the Material plane helps both environments. Prevents magical stagnation in the Astral plane. In the material plane, its not just for magical beings, but the health of the planet itself. It’s all one big cycle. The Isles have been somewhat healthy because of the leylines that run underneath the land. They directly feed magic from the Astral plane into the Material. But they have not been maintained properly." The lack of rites and Fey have caused that.
