Gothica
From Tardis Wiki, the free Doctor Who reference
Gothica was a colony with cathedrals. On 20 October 2820, Gothica's cathedrals were suddenly filled with people claiming to be from the future, who warned that in one hundred years and two days, the colony would be overrun by Weeping Angels.
The warning came true on 22 October 2920, with many people being sent into the past. (PROSE: Time Traveller's Diary)
