Skerth

From Tardis Wiki, the free Doctor Who reference

The Skerth (PROSE: A History of Humankind) once existed in a parallel universe. They built a spacecraft which at some point crashed and became linked with the Fancy, a sailing ship from Earth in the 1690s. All those aboard the ship died from a disease, which the Eleventh Doctor claimed to be a common cold. (TV: The Curse of the Black Spot)
