Aetherstorm

Aetherstorms are dangerous storms of aether, full of charged particles, time dilated and interdimensional in nature, in which anything in the area becomes incorporeal, shifting in and out of dimensions, and where sound is only a broken echo. People and objects may be spontaneously teleported to randomized locations and planes, or become stretched thin in areas of warped spacetime, become disassociated, or spontaneously disintegrate.
To conjure an aetherstorm would require significantly increased magical power, provided by an aether orb, or a group of mages with combined power.
