Members of the Psy Race can be born with any number of psychic abilities. The following is a list of the ones described so far.
They are rated on a Gradient, going from lower class (<3.4) over middle class (<6.4) to upper class (<10). Psy higher than 10 are called Cardinals and have distinctive black eyes with stars in them.
Members of the Psy Race are usually referred to by their dominant talent. Therefore Faith Nightstar is considered an F-Psy even though she also has considerable telepathy.
This list is incomplete.
Anchors
Anchors are essential to the PsyNet's function. They give the net shape and help keep it stable. However Anchors themselves are strongly inclined towards homocidal sociopathy.
Empaths (E-Psy)
Empaths specialize in emotion. They can sense emotions, heal emotional wounds by taking a person's pain into themselves, amplify certain emotions and dampen others. Empaths cannot be Silenced, therefore since 1971 they have been categorized as "Non Specialized" and brainwashed into believing that they have no accessible powers at all.
Foreseers (F-Psy)
Have the ability to see the future. Prior to the implementation of the Silence Protocol, Foreseers frequently worked with law enforcement. Afterwards they focused on making business forecasts.
Backsight
This is an offshoot of Foresight and involves the ability to see the past as it occurred. All F-Psy have the capacity for backsight but not everybody with backsight can see the future.
M-Psy
The M-Psy are the doctors and scientists of the Psy world. Their abilities vary greatly and range from the ability to see into the body to the ability to see into the DNA. Some are also capable of healing.
Telekinetics (Tk-Psy)
Telekinetics have the ability to move objects witihout touching them. The weakest Tks are limited to beinga ble to turn on the lights, but the strongest can transport themselves and others across vast distances. Kaleb Krychek is a Cardinal Tk.
Tk-Cell
Tk-Cell is a mutation of the telekinetic ability that grants (or curses) a person with the ability to move things on the cellular level. This is one of the more dangerous psychic talents one can be born with since a fit of temper can cause to someone with the ability to accidently kill another. Prior to the implementation of Silence Tk-Cells almost always ended up in prison for murder. Those who avoided this fate did so by avoiding other people entirely.
Travelers (Tk-V)
Travelers are natural teleporters. They can teleport themselves and others as easily as others telepath. Currently Vasic is the only known Traveler.
Telepaths (Tp-Psy)
All members of the Psy race have to have at least some telepathy in order to make and hold a connection to the PsyNet. Therefore Telepathy is easily the most common talent in the Psy World. Within the this ability are serveral specialties though.
Justice Psy (J-Psy)
J-Psy are telepaths with the ability to retrieve memories and broadcast them to others, including those with no telepathic abilities at all. Examples include Sophia Russo.
Pure Telepaths
Pure telepaths facilitate communication between two parties. Since telepathy cannot be traced or recorded it is highly secure. Examples of pure telepaths include Henry Scott and Maureen NightStar.
Viral Transmitters
Viral transmitters have the ability to induce insanity (sometime temporarily, sometimes deathly permanent) into a person. Nikita Duncan is the considered the best viral transmitter in the net, but Kaleb Krychek may also have some form of this ability as well.
X-Psy
Dual Cardinal Psy
Dual Cardinal's are Psy who have Cardinal level power in any two psychic abilities. As of ToN (the latest book), there is only one known Psy in existence who has Dual Cardinal ability - Kaleb Krychek. Both is Telekinesis and Telepathy are of Cardinal level.
