" The waters which we spread upon the desert have become blood. Blood upon our land! Behold our desert which could
rejoice and blossom; it has lured the stranger and seduced him in our midst.
They come for violence! Their faces are closed up as for the last wind of
Kralizec! They gather the captivity of the sand. They suck up the abundance of
the sand, the treasure hidden in the depths. Behold them as they go forth to
their evil work. It is written: 'And I stood upon the sand, and I saw a beast
rise up out of that sand, and upon the head of that beast was the name of God! "

― Frank Herbert , Children of Dune (Dune, #3)
