Sue-wraith

Sue-wraiths, aka "Author-wraiths" or "Sue/Stu/Ooh phantoms", are spirits created by the author of a fic. Sue-wraiths inhabit possessed characters, causing them act extremely out of character. If an exorcism is performed, the wraith will coalesce from the bodies of the characters, and more often than not, whine at the exorciser. Those that inhabit slashed characters have also been called slash dwimmerlaiks.

A CAD pointed at a possessed character will usually (but not always) reveal the character's Possessed status. It will also show a very high OOC reading, which tends to be around 70-99%.

Sue-wraiths have no fixed form, and are physically helpless, being basically a sort of sentient mist. They usually dissipate quickly after being removed from a character, and are absorbed back into the Multiverse, but may on occasion, if belonging to a particularly persistent author, attempt to re-possess a character. They may also be caught in jars and subjected to experiments.

Sue-wraiths have been known to possess agents if the exorcists aren't careful, as happened to Agent Drake. These can be displaced by exorcism as usual.
