Age of Ruins
Aezeim (pronounced Ay-zee-um) is the powder that remained after residuum and magical items were destroyed by the Cataclysm. During the Age of Darkness aezeim in the upper atmosphere significantly reduced the intensity of sunlight in the effected areas. Gradually the aezeim in the atmosphere dissipated and now it only exists on the surface. under some conditions it can be swept up by winds for short periods of time and can cause respiratory diseases in those who inhale the particles.
