Known by the Doctor as Silents, these genetically engineered 7 foot tall mouthless creatures are confessional priests of the Church of the Silence. Anyone looking at a Silent will immediately forget them the moment they looked away, meaning sinners could make their confessions without remembering they had done so afterwards.

Silents are capable of obliterating enemies by absorbing electrical energy from the air and discharging it from their hands at a vastly more potent level. They are incredibly resilient creatures and strong enough to smash down reinforced barriers with their elongated hands.
