Deep Darkness
From Tardis Wiki, the free Doctor Who reference
The Deep Darkness was either a void, a pocket universe or some kind of dimension that existed outside Normal Space. During the Dark Times of the universe, the Eternals banished the witch-like Carrionites and the Hervoken to the Deep Darkness.
Three Carrionites escaped from the void and in 1599 opened a gateway between Earth and the Deep Darkness. All trapped Carrionites began to enter Earth but the gateway was closed by the brilliant words of William Shakespeare with the help of the Tenth Doctor and Martha Jones. (TV: The Shakespeare Code)
