Shakkad Station was a deep desert sandworm and melange research base on Chapterhouse, during the time of Kralizec. The ultra-remote base had been founded by the New Sisterhood as a place to gather data on the sandworms that had been desertifying the ecology of Chapterhouse from a previous climate of deciduous plant life. The research base was named in honor of the famed Imperial chemist, Shakkad, who had first reported on the beneficial properties of spice, over fifteen thousand years earlier, even before the Butlerian Jihad, when he had been surveying Rakis.
