The Silence was a religious order who considered themselves the “Sentinels of History”. They tried to kill the Doctor because of a specific prophecy, which stated: “On the fields of Trenzalore, at the fall of the eleventh, when no living creature can speak falsely or fail to answer, a Question will be asked, a question that must never, ever be answered.”

This question was “The First Question, the oldest question in the Universe, that must never be answered, hidden in plain sight.” Dorium Maldovar told the Eleventh Doctor that the question was: “Doctor Who?”, which was a question the Doctor had been apparently running from his entire life.

The Silence was led by a race of aliens who would be erased from your memory after you looked away from them (known as Silents) who used post-hypnotic suggestion to manipulate other species into doing their bidding. The Silents also employed human or humanoid agents to carry out specific tasks. These agents were often fitted with Eye Drives which allowed them to remember the Silents.

They were the primary villains of (new) Series 6.
