The silents are enemies of the eleventh doctor . They are based on slenderman , a german myth about a shape shifting monster who kidnapps children . They are also based on The scream , a painting full of weird creatures .

The questionEdit

The question is what the silents fear most . The silents belive that if the question is asked Silence will fall (in other words , the univerce wil end).

In the episode The wedding of River Song , Dorium Maldovar , a talking head , told the doctor that the question was the first question ever , and it had been following the doctor ever since the events of An Unearthly child . He also revealled that the question was Doctor Who?
