Dispelling Illusions

Always meddling... The Infinite Dragonflight seek to disrupt history as we have come to know it by deceiving Prince Arthas. If they can convince him that none of the grain here carries the plague, then he'll never have to make the fateful decision to cull Stratholme. This must not come to pass. Use this Arcane Disruptor on any suspicious crates of grain you find to reveal them for what they are. Meet me near Stratholme's entrance, north of this place, when the work is done.
