Wraiths

Wraiths are powerful psionic beings that terrify the living heck out of every other race, pretty much.

General Information
Little is known about Wraiths, except that they are believed to feed on fear and are capable of manipulating other races. To what degree remains a mystery, since they, strangely enough, rarely do so.

Abilities and Limitations
Wraiths are considered to be the best investigators available. They charge quite a price for it, though no one knows what they do with the money. Their investigative method is unknown, though it is unquestionably either magic or extrasensory.

They are able to read minds, though only if you do not care about the state of said mind when it is over with; for few can survive a mental probe by one of these terrifying creatures.
