Warpscrolls are powerful magic items inscribed upon the hide of living creatures using a special ink made from warpstone and the blood of an enemy slain through treachery. The ink causes agony and eventual death, but to be fully effective the hide must he flayed from the creature while it is still alive, and then cured using finely ground warpstone powder. When the potent spell upon the warpscroll is cast its victims suffer rapid and irreversible aging, shrivelling and dying in seconds. As their words are read aloud, the parchment crumbles to dust.
