Silent Sisters

The silent sisters are an organisation of women sworn to the service of the Stranger, one of the aspects of the god in the Faith of the Seven. The Stranger represents death. The silent sisters, who have taken vows of silence, dress and prepare the bodies of the dead for funerals.

Season 1
Silent sisters dress and prepare the bodies of Lord Jon Arryn and, later, Ser Hugh of the Vale for burial.

In the books
In the Song of Ice and Fire novels, the silent sisters, sometimes called Wives of the Stranger, are considered holy and inviolate. They wear grey cowls which hide their faces apart from their eyes.
