Parmenides of Elea's Tunic

Origin
Parmenides of Elea was a pre-Socratic Greek philosopher from Elea in Southern Italy who founded his own school of thought, the Eleatics. They believed against using the senses to judge the universe, as things perceived by them were too inconsistent and contradictory. In his only surviving work, On Nature, describes two separate stream of reality in existence. The world of truth is static, barren and uniformly unmade, where nothingness spawns itself, while opinion and sensation is the universe we choose to obliviously inhabit. Although he easily understood an idea as advanced as conservation of energy in a finite universe, his theories had difficulty grasping around the definition of non-existence and the void central to his theory.

Effects
Sends the wearer to a reality which they make-up themselves, governed by most fundamental laws that our own possesses. Specific and conscious changes occur only gradually, while spontaneous outbursts can cause radical alterations. After a time, the world will act independently of the user without their input. This is due to their body and mind being physically shredded into pure nothingness while operating. After their essence is fully devastated, the world will try to reestablish a link, locate none and quickly crumble apart.
