Psychic Skills are broken into two main groups, the Psi-Gamma and the Psi-Kappa.
Psi Gamma is: psychic cognition. Empathy, Telepathy, and Precognition all fall under Psi-Gamma.
Psi-Kappa is: psychic action. All Psychokinesis abilities fall under Psi-Kappa.
Psychic Ability is measured on a numbered scale. Each of the 4 main Classes or skill sets, Precognition, Empathy, Telepathy, and Psychokinesis, have their own scales. In each case the scale is form 0 to 500. There has never been any one above 300 to date. The scale is broken in to Public scale, Official scale, and the Classified scale. To the general public's knowledge the scale only goes to 50. The official scale goes to 200. Any thing above 200 is Classified. With the exception of the Precognitive Scale all other scales have a subjective portion.
Precognitive Scale is based on ones ability to see into the past or future. The farther one can see the higher the level. Any one able to see past 500 years in either direction is classed as a level 500. By the same token any one able to see under 1 year is classed as a 0. Ones level the farthest distance in time one can see.
Empathic Scale is based on the degree of transference in either direction as well as how far away from the source or recipient the Empath is able to be. As well as the quantity of people able to be effected.
Telepathic Scale is based on how much you can read thoughts and memory, implant ideas or behavior, or manipulate the action and thoughts of a subject, also the ability to communicate. As well as how far away from the subject the Telepath is able to be. As well as the quantity of people able to be effected.
Psychokinetic Scale is based on different things for the 4 subclasses.
Telekinetic Scale is based on mass of the object, length and amount of control and distance from the object.
Pyrokinetic Scale is based temperature of the flames produced, length of control, radius of effect-how far can you produce or manipulate the flame or heat-, and the degree of temperature that can be raised in an object as well as the ability to manipulate a flame or produce a flame. i.e.. can you make it do thing in the air and on the ground and can your flames take form.
Cryokinetic Scale is based on the temperature of the ice produced, radius of effect-how far can you produce or manipulate the ice or cold, the degree of temperature that can be lowered in an object, as well as the ability to manipulate the ice or produce ice. i.e.. can you make it do thing in the air and on the ground and can your ice take form.
Hydrokinetic Scale is based on the amount and density of the water produced, the volume that can be controlled, the length and amount of control, as well as the ability to manipulate water or produce water i.e.. can you make it do thing in the air and on the ground and can your water take form.
People With all 4 main classes, and all subclasses are called Complete or Full Psychics any one with any less than all 4 classes and all subclasses is considered to be a Partial or Incomplete Psychic. Complete Psychics are rare out side the Imperial line, and the Military. Most Psychics above level 50 are employed by the Empire. A Level 100 or above out side of the Imperial Family, Justial Conclave/Council, Special Forces, or Health Service are practically unknown.
The Empathic Class has 2 subclasses not every one has both. There is Emotional Empathy and Physical Empathy. Not every one has the ability to send and read. People with high level of ability's in Empathy are usually Doctors and Therapists. Although the Imperial Family, Justial Conclave/Council, and Special Forces all use it for other proposes.
Emotional Empaths can feel or manipulate your emotions. If they can only feel emotions there called a reader. If they can manipulate them their called a broadcaster or transmitter. If They can due both there a complete or full Emotional Empath.
Physical Empaths can feel or manipulate your physical pain or pleasure and other physical sensations. If they can only feel physical sensations there called a reader. If they can manipulate them their called a broadcaster or transmitter. If They can due both there a complete or full Physical Empath.
Telepathic Class has no subclasses but people do full in to one of three categories. Broadcaster or Transmitter, Reader, or Two-way also know as a complete or full Telepath. A Broadcaster can send to anyone, everyone, or one in particular. A reader is able to read or hear what is in a persons mind. The Justial's are among the highest scaled Telepaths known.
Psychokinetic Class has 4 subclasses not every one has all 4. There is Telekinesis, Pyrokinesis, Cryokinesis, Hydrokinesis. Every Psychokinetic has at least Telekinesis.
Telekinesis: the the ability to move objects with thought alone.
Pyrokinesis: the ability to manipulate and produce fire as well as control the heat in an object. Coupled with Telekinesis this subclass can become a formidable offensive weapon.
Hydrokinesis: the ability to manipulate and produce water. With this skill one does make water but rather gathers it. Coupled with Telekinesis one can make the water gathered fly in the air. If the Hydrokinetic has Cryokinesis as well the water can be turned in to ice. When combining Hydrokinesis, Cryokinesis, and Telekinesis the result can be a formidable offensive weapon.
Cryokinesis: the the ability to manipulate and produce ice as well as control the coldness of an object. It is the opposite of Pyrokinesis. With this skill one can literally freeze an object. If the Cryokinetic has Hydrokinesis as well the water can be turned in to ice. When combining Hydrokinesis, Cryokinesis, and Telekinesis the result can be a formidable offensive weapon.
Precognitive Class while the name is inaccurate Precognition is the ability to see the flow of time. It has no Subclasses but a PreCog can see both direction. Visions of the future some times come as symbolic visions and some times literal visions. Seeing the past is always literal. It has been known that some times the future is shaded or completely hidden.
