The Spice Melange is the most powerful substance in the Universe. The Spice enables all interstellar space travel, allowing the Spice-mutated Guild Navigators to warp the fabric of space. Without the Spice, our Bene Gesserit Sisterhood can have no visions, no future Sight. With the Spice, human life can be extended by hundreds of years.

In all the Galaxy, Spice is found only on the planet Arrakis. The native Fremen possess the Blue-Within-Blue eyes indicative of Spice saturation. Spice is harvested from the desert Spice fields, and exported throughout the Empire. Without the Spice, the Padishah Emperor would have no empire.

We watch Arrakis closely now. We must, beyond all else, insure our Spice allotments are not interrupted -

The Spice must flow.
