"My lord, I suspect so much. I think the Fremen are the allies we seek. They are strong, fierce. They do not give their loyalty easily or quickly. As you know, the Imperium has never been able to take a census of the Fremen. Everyone thinks that there are but few wandering here and there in the desert. My lord, I suspect an incredible secret has been kept on this planet, that the Fremen exist in vast numbers—vast—and it is they who control Arrakis."
