Sue-wraith

Author-wraiths, aka Sue/Stu/Ooh phantoms, are the spirits of the author that inhabit possessed characters. If an exorcism is performed, these are what 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.

They have no fixed from, 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.
