Demons Run
From Tardis Wiki, the free Doctor Who reference
Demon's Run was an asteroid where Amy Pond was held prisoner by Madame Kovarian and her associates, the Anglican Regiment of the Church.
On this asteroid, Amy gave birth to her daughter Melody (or as she was more commonly known, River Song). The Eleventh Doctor, Rory and a force of allies stormed Demon's Run and rescued Amy, but Kovarian escaped with Melody. Melody's future self, River Song, appeared after the battle to reveal her true identity. The Doctor then departed the asteroid alone, to find the infant Melody. (DW: A Good Man Goes to War).
There is a saying that goes with Demon's Run: "Demon's Run - when a good man goes to war" ; a clear reference to the episode title.
