Dresden Files

Ghost dust is a substance used to fight ghosts. It first appears in Grave Peril.


The whole point of the ghost dust was that it was something extra-real, that it was heavy and inert and locked spiritual matter into place when it touched it.Harry Dresden[1]

Made from depleted uranium, cold iron, basil and some sort of dung,[1] ghost dust affects ghosts even in the mortal plane. Upon contact, it sparks into "blazing motes of scarlet light", apparently causing them pain and immobilizing their ectoplasmic flesh.[2]

In the Nevernever, the weight of the ghost dust increases significantly, weighing "thirty or forty pounds" for a small pouch. Dresden believes that, if released, it would tear a hole in the Nevernever.[1]

In the series[]

Grave Peril[]

In Grave Peril, Harry Dresden uses it to fight ghosts.[1] He dumps his remaining ghost dust onto the Leanansidhe, causing her to scream as her skin tears and burns.[3]

Ghost Story[]

In Ghost Story, Mortimer Lindquist has a variation of ghost dust mixed into the paint in his house to prevent ghosts from entering. It is apparently made with a different recipe than the one Dresden uses.[4]
