Higher-Dimensional Physiology

Summary
Higher-Dimensional Physiology (also called Transcendent Physiology) refers to a state of being that transcends the level/plane/layer/mathematical  proportions of third-dimensional space.

Applications

 * Non-Corporeality: Many higher dimensional beings lack true physical bodies.
 * A degree of Immunity toward Space-Time Manipulation, Physics Manipulation, Mathematics Manipulation, Causality Manipulation, ect.: Higher-dimensional beings are by default immune to the laws of physics of lower-dimensional spaces, as they transcend such lower-dimensional spaces.
 * Incredible power: Per definition, all higher-dimensional entities possess infinite volume by 3-dimensional standards, and as such also infinite mass, and energy/power. Infinity in projective geometry states that 4-dimensional beings are an infinite number of times greater compared to 3-dimensional space; 5-dimensional entities are similarly greater compared to 4-dimensional space; and so onwards.
 * Potential Time Travel or Dimensional Travel: Due to the user's status as being part of a higher dimension, the user may move through time as easily a three-dimensional entity might traverse though ground.
 * Etcetera...

Limitations

 * May be unable to physically interact with lower dimensions, forcing them to create "Avatars" or act through other beings (Possession)
 * May be vulnerable to even higher-dimensional entities, if there is such a thing.
 * Vulnerable to Higher-Dimensional Manipulation
