Doctor: Inscriptions on the floor...
Graham: What is it—some sort of cave painting?
Doctor: Almost. Left by the people who worked here.
Graham: Can you read it? What does it say?
Doctor: (translating) "We are scientists. Abducted, tortured and made to work, while our families are held hostage. We are forced to find new ways of destruction. Poisons, weapons, creatures. We gave them our minds and they made us the creators of death. This planet has been left scorched and barren from our work. The atmosphere and water are toxic. Killing machines and creatures inhabit every corner. We had no choice but to obey the Stenza. We are trying to destroy all of our work before they use it against others." There's two words below that: "They're coming." That's how it ends.
— Doctor Who, "The Ghost Monument"
