house of the hearth...where orphans who had the potential are enlisted in the fatui. It was ran by the Knave, called 'father' to the children. There's a 'mother' too, but only the eldest knew about her...lyney accidentally found out about her by walking past the office of 'father' in the middle of the night

lyney was currently watching 'father' teach the newer children the basics. He could feel eyes on the back of his head. He turned and saw 'mother' was watching him
