The Sisters of Silence, also known as the "Silent Sisterhood," the "Witch-Seekers," the "Pale Scourge," the "Soulless Ones," the "Null Maidens," the "Eyrine" and the "Daughters of the Abyss," were once the militant arm of the Adeptus Astra Telepathica and were referred to internally within the records of the Adeptus Terra as the Departmento Investigates. They are an all-female order of Imperial Witch Hunters and soulless psychic Nulls tasked with hunting down renegade psykers and other psychic threats across the galaxy. They also help to enforce the Imperium's rigid laws on the use of psychic powers.
