Mind-melds – An ancient Vulcan ritual in which two persons are telepathically linked, sharing each other’s consciousness. To Vulcans, mind-melding is a deeply personal experience, providing an intense intimacy. Scientifically the process is described as a synaptic pattern displacement. A mind-meld can be used to hone another’s telepathic skill, bear in mind that their must be some latent skill to start with.

Empathy – The ability to sense/feel another emotions or mood. 

Telekinesis – The ability to move objects with the power of your mind. (Unique to Captain Lorien. Not used anywhere else on Federation Space.) 

Precognition – The ability to sense events before they happen. (Not used on Federation Space.) 

Clairvoyance – The perception of things beyond the natural range of the senses. (Not used on Federation Space.)   

It is of course fine to pick up random thoughts or read what could be called a person’s ‘public mind’, which is basically their internal dialog. Internal dialog is the voice in your mind, when you and debating or thinking of a way to word something properly, though to be heard by telepaths, you would have to be ‘broadcasting’ this dialogue or emotion. Most telepathic races have natural ability to shield from reading too deeply unless they are consciously will themselves to do so. More on this is explained below.

Social Telepathy:
Telepathy is the central organizational theme of Betazoid society.  Among their own people, Betazoids communicate telepathically.  Betazoid towns and cities are filled with an undisturbed (some off-worlders may say eerie) silence.  Many resort to speech among non-Betazoids, out of respect, though this isn't universal.  Betazoids dislike species whose minds they cannot read, such as the Ferengi, Breen, and Dopterians, feeling uncomfortable in their presence; this remains their only unresolved prejudice.  Betazoids who lose their telepathic ability feel handicapped, frightened, and alone, with many choosing to lead their telepathically mute lives off-world among other non-telepaths.

Code of Sentience:
The Code of Sentience guides Betazoids in their use of telepathy among non-telepaths.  Individual Betazoids follow it to a lesser or greater degree, each according to his or her nature.  Like any social code, it outlines what is acceptable, proper behavior, to both reassure non-telepaths and safeguard Betazoids:

• Reading the mind of another without his knowledge is taboo.
• Even when permission has been granted, the code forbids reading thoughts separate from the purpose of the mind reading.
• The code discourages a Betazoid from divulging what he reads to another without permission.
• It is considered rude for Betazoids to communicate telepathically with each other in the presence of non-telepaths.
   

Acceptable Use in Game:
There is no telepathic Universal Translator. That means if a Klingon is thinking to him or herself, a Betazoid is not going to be able to read that person's mind, unless they also speak Klingon. Same as with a Valtese trying to read the mind of a Betazoid, etc. Empathy also works the same way. If an empathic player suddenly came across an unknown alien race, they wouldn't be able to suddenly know what the aliens are thinking, as there is no point of reference. Anger may not feel like anger in every species of the galaxy. Be careful and use common sense when trying to use telepathy and empathy within the game.
