Metaphysics desires to examine the fundamental nature of reality, specifically by examining the forces that can allow someone's will to manipulate it. For most laypeople, metaphysics explores the forces that are seen as transgression of the natural laws as understood by physics, though those in the field say that these "supernatural forces" are not really separate from natural mechanics, rather a part of a whole. This includes large fields such as Magic, which changes events through Mana. There is Psychokinesis where one can manipulate the world using Psychokinetic Energy. And there is Neijing, the conscious control of a living being's internal energy to perform preternatural feats in order to gain advantages in combat or attain a higher level of understanding.
