Silkies are female spirits, dressed in rustling silk, that inhabit the borderlands between England and Scotland. According to lore, silkies perform household chores and are valued by people living in large houses. But silkies can be perverse, too; a house that is tidy might be left disarranged, and a messy house might be put in order. A silky also can act as the guardian of a house, killing any intruder suspected of being out for harm.
