Dimensional Warfare

Dimensional Warfare is a type of warfare in which separate planes, dimensions, and realms fight eachother using a variety of inter-dimensional weaponry and portals. It was first applied during the Great Dimensional War.

The Rift Breaker
The Rift Breaker was a machine developed by the Cave Goblins to create a weapon that could harm or destroy realms without having to be placed within that realm. It was heavily used during the Great Dimensional War by the Misthalinians to fire at centaur and fairy planes, however, it was banned by the armistice of 312.
