Divergent Universe is an arc in the Big Finish Doctor Who dramas starring the Eighth Doctor, Charlotte "Charlie" Pollard and their alien fuckboy Carys. The Doctor visited Gallifrey and found more fucked-up stories from the past. After visiting the place where people who were erased went, he spent some time finding out that Rassilon is a bigoted cunt. Turned out, back in the day, Rassilon was fond of throwing things he disliked into another universe. Those Divergents, those drug-addicted Paki sodomites... Sorry, that was my political program for the next City Council election. Point is, he exiled some folks into another universe where time does not exist. Now the Doctor is also there without his TARDIS and it's time for some heavy mindfuck.
