Riven Earth is a weave uses flows of Earth and Fire.
This weave is associated with the Talent Earth Singing. It affects a stretch of ground by causing it to explode. The earth erupts and causes devastation to any ground force, such as an army, which is unfortunate enough to stand above it. What is left behind is a long line of charred and churned earth. This weave does not have to start at the channelers location, but can run perpendicular.
