A xorn can phase through solid rock. Due to its unusual body chemistry, It has no need to breathe. It has a thick hide. It eats metal.

A distant cousin of the earth elemental, the xorn has the ability to shift the cells of its body around in such a way that it becomes porous to inert material. This gives it the ability to pass through any obstacle that might be between it and its next meal.
