12.4.1 THE ELEMENTAL PLANE OF EARTH

The elemental plane of Earth was once a glittering plane of rocks and gems 
until it was corrupted by the Taint, turning the earth itself into a 
diseased miasma of foulness. The creatures there are twisted abominations 
and many go mad just trying to navigate through its twisting tunnels and 
mountains. It is no wonder that Geomancers who tap into this plane are 
considered somewhat insane.
