Casters only need to use a large amount of water to eradicate these colossal creatures hidden at least hundreds of meters underground.
But the larvae of sandworms, sand trout, require a vast amount of moisture to grow, which is the reason for the planet's desertification.
This magical transformation surprised Karon.
The Ancestral Red Dragon's dark golden pupils gleamed. Through the information carried by the sky and the earth, he could feel the reverence and faith of the Fremen towards the desert. The belief brought by the mystical creatures, sandworms, was proof of the Fremen's awe of nature and mighty power.
He also sensed the longing and pursuit of water and forest by the Fremen, amidst the god-making rhetoric spread by the Sisterhood.
The ultimate Savior, the Messiah, will descend from beyond the skies, bringing abundant water and green plants to the Fremen, transforming this desert planet into a paradise where the Fremen can walk and live.
