Invisible Stalker

A powerful magical force created from the energy of the Ethereal Plane by skilled conjurers Invisible Stalkers are potent assassins capable of moving with ease to their unsuspecting victims only to deliver a cruel horrific death. Perceiving the being is possible only in the Ethereal plane or with magic that reveals the invisible but the latter only gives a vague outline of the being. It is however possible to feel and hear the stalkers presence as it passes.
Creating an Invisible Stalker is extremely difficult with the knowledge to do so restricted in most magical school and thus existing in a handful of tomes across Aesalia. Those with the capability however are often sought as much as allies as to be assassinated by conventional means to prevent their power being used against nearby forces.
