Hollograd at Christmas. (COMIC: Red Christmas)
Hollograd was a village that the Eleventh Doctor took Amy Pond to visit in 1873. Expecting to find it all Christmassy on Christmas Eve, they discovered it was instead engulfed in a red psychic mist and the Krampus were feasting on the sadness and fear of the villagers as they found themselves separated from their children.
