The Republic of Heaven (слэш)

His Dark Materials AU. John and his dæmon, Amarisa, have never quite fit in, largely because she settled as a wolfdog. Sherlock and Raniel are similarly isolated, mostly because the woman they call Mummy is a witch. These two men and their dæmons end up sharing a flat together and the rest, as they say, is history. And with a witch-clan out for John's blood and a man known as Moriarty emerging from the shadows, they're certainly not going to be bored.
