VORTEX

 Swirling clouds of pure elemental energies, the vortices are thought to be related to the larger elementals. Though the vortices do no damage when touched, they are noted for being able to envelop unwary travellers. The hapless fool thus swallowed by a vortex will soon perish from exposure to the element the vortex is composed of.
