Wraiths

When a mortal dies a violent death or has unfinished business, it is hard to let go of this world and so a wraith is born.

Ghosts. Phantoms. The restless dead. Call them what you like, these malingering spirits of departed mortals have been around as long as Cainites have, perhaps longer.
Wraiths are undead creatures that can be confused with shadows or mist, they are incorporeal but when in presence of mortals they feed upon the emotions that mortals have. Fear and Anger most likely since every Wraith has the Dark Presence about them.
Ever felt an uncontrollable fear for no reason what so ever?? sitting infront of your Pc and suddenly a shiver down your spine and a sense of Dread that comes with it? Thar is the Dark Presence roaming around and whenever you are close to a Wraith the Dark Presence follows.
When fueled by anger or fear a Wraith can manifest itself and interact with the living, The invisibly hurled plate, the sourceless whisper, the worm-riddled visage that flickers at the edge of perception all of these are powers that Wraiths possess, but when in contact with another supernatural being, a Wraith can try to consume it and pour all its hatred and malice on to it, all Wraiths are evil and wish for every creature in this earth to experience the pain and suffering they went and are still going through.

Wraiths manifest most effectively in "haunted" sites and places where great suffering or trauma has left a psychic residue (battlefields, torture chambers, the bridge where a suicide leapt, etc. ). In such places, the Shroud between the worlds of the living and the dead is weak

a Wraith is but the first step into something else, but no mortal can say if it is for good or ill.
