"I see them. The Dementors are smothering the Sarsen stones..." As as Sarsen stone went dark, the ring of Dementors seemed to increase their "breath', and Narcissa wondered if they were breathing in whatever Magic was there. Some of the floating robed figures slowly went and switched places, taking over the work of lifting the bluestones. This was a pattern for them now; the Dementors were working together in a routine in order to feed off of the stones... Cissy gasped as she realized that they were essentially working like leeches and draining magic out of the world.
