Alia’s entire performance rests on the melange that fills the chalice. Melange heightens Alia’s ability to see the future, and therefore shrouds her in a prophetic state worthy of the pilgrims’ worship. Furthermore, the pilgrims are all vitally addicted to melange, and their dependence therefore strengthens their reverence for Alia, since she’s the person who can provide them with it. In this light, the sway that Alia holds over everyone is disingenuous, since it’s dependent on a manipulative, weaponized drug.
