March

Elemental marches are what happens when elementals band together and invade other realms in an attempt to expand their domain. The most commonly encountered invasions by mortal populations are Earthmarches, when the elemental population of Deep Mountain bands together to conquer the surface world.

The most devastating invasions are Firemarches, in which fire elementals will invade a solar system through their luminary. Common outcomes of Firemarches are the creation of new stars. Even Wildspace is not safe from the cancerous spread of fire elementals, as it too can be dragged down into the Burning Domain.

Watermarches are similar to Earthmarches, in that the native population of a planet will rise up and conquer the world. Most often this involves pulling the continents beneath the ocean, with successful invasions turning continental worlds into ocean worlds.

Airmarches are the most rare of the four. Air elementals are a fickle sort, more likely to invade and destroy one another as they are anyone else. Airmarches commonly take the form of hurricanes, tornadoes, lightning storms and other similar weather systems. The most devastating of Airmarches are hurricanes; continent spanning super storms with monstrously high wind speeds, though thankfully are rare enough.
