Journals of the Old Faith (Cult of the Lamb AU(?) Fanfic)

It's not often someone would join an unknown cult, let alone stumble upon it by pure chance. However, that's what managed to happen. A human had run away from their home, and found a new one deep in nature, though to their surprise, they wouldn't be staying human in this home. The now former human had come across cultlands unknown to humans, and their life was changed forever upon meeting the Bishops of the Old Faith. Will they ever get used to their new home, now as something else they had never expected to be? What will be in store for them? What can they learn? These questions, as well as many more, will be answered as the one formerly known as Leaf go through cult life. Feel free to read about everything they see, learn, and much more. They know they'll be writing it all down.
