All major mind powers in Eldahar can be classed into 5 catagories as laid out in Julian May's excellant Sci-fi series, "The Many Coloured Land". For more information, read these books.

These catagories are;-

Farsensing, Redaction, Coercion, Creation and Psychokinesis.

Other mental abilities exist, but are a lot more rare.

Anyone possessing mental powers is said to be using Sorcery, as opposed to straight forward magic.

All mental powers originate from the Seven races and those rebel humans who brought about the destruction of Sha'lean, the Qual homeworld.

See Metapsychics.

As everything on Eldahar involves using spirit, far sensing is no exception. It is possible to send one or more mental senses out of the body (ie hearing and sight) to scry at a distance. It is also possible to send the entire mind out and project it somewhere else. Coupled with creation, a far sensor can "create" an illusionary or even seemingly solid image of his/herself (a form of spiritual projection).

Deep sight (X-ray vision)

Sense psychic impressions, past and future.

Whereas in Far sensing, the things projected to another mind only brush the surface of consciousness, with redaction, it is possible to plung into the unconscious mind, into dreams and even coma's.

Self regeneration

Split consciousness into independantly thinking parts.

Psychocreative shields (to protect against practically anything)

When the Titans lost control of the World's Heart in the Yr 0 of occupation, the entire aspect of the World's Heart changed (wavelength / frequency) resulting in all Titan created objects relying on the Heart's energy becoming useless to the new settlers. The new settlers became a different Set in the World's Heart and began through discovery of Titan methods, new methods of their own, beliefs and exploration, to create their own Heart items.
Below are the methods so far employed.

Plug in POW to use.
These items have a spiritual resevoir
that needs to be filled by direct contact with a living spirit. A sacrifice of POW is normally required to fuel the item temporarily. (for one charge) 

Self-charging and storing.
These items soak themselves in the natural energies existing on the astral plane and recharge themselves at different rates depending on the material used, skill of the
enchanter and ability imbued. 

Recharge necessary.
These items have no way of soaking energy back to recharge themselves but 
must unlocked, charged by ritual and then lockedagain to keep the charge in. 

Continuous charges.
These items have such an efficient rate of astral soak that for every activation
they regain back the same amount from the area and their own magical reaction. 

Continuous working.
These items have a very low energy consumption and are nearly always 
only able to work when fueling off a living aura or near an astral node. Items such as these
usually "tick over" on the aura-burn until the aura fluctuates in a defined manner; then the main functions fire-off. ie a Ring of Protection fuels itself when the person isn't being attacked. It may be  possible with some ROP's to burn all their energy, but usually when a person is under attack, their aura's are fired up far more than normal and a ROP will fuel itself very quickly.

Aura-activated.
These items come in different degrees of complexity. The simplest AA's are those where you just concentrate on the item and bingo. Next comes those AA's where you have to imagine a rune and fit it to a lock in the item's spirit. Then comes the AA where you have to think specific thoughts to fit a lock. Finally the AA's where POW has to be channelled directly into the item, requiring the AA and the activator to assume similar surface auras. 

Types of Enchantment 

Runaic 122 letters of the Runaic alphabet.

Runes 154 base runes - variously interpreted.

Star-magic Elven - Pre-E-Har, derived from mental energy.

Binding of spirits within objects.

Divine Objects whose aura's have been completely displaced to an astral pool apart from the cord connection through which belief is channelled. These objects appear to have no spirit whatsoever, but infact have a resevoir of it floating high on the astral plane.

Will-imposing. Requires huge level of consciousness and self-belief aka "Mental-creation".

Technological. Different Set of belief in the World's Heart.

Titanesque. Different Set of belief in the World's Heart.

Speciality in spell craeft, runes and wards.
