The second Arya chapter in AFFC. The kindly man was educating Arya about the Facless men orgin. He talks about the slaves in Valyria's mines and how the first Faceless man gave the gift of death to a slave Arya says "'He killed the slave?' That did not sound right. 'He should have killed the Masters!' 'He would bring the gift to them as well...but that is a tale for another day, one best shared with no one.'" Now I dismissed this the first time i read AFFC but as I am reading this again and I really like the details from the past especially Valyria, which is why it stuck out in my mind. I mean all we really know about Valyria is that it basically rulled everything but the seven kingdoms. With Magic, Dragons, and Legions of Legionairs. Its downfall came from a Volcano erruption, and somehow all the Valyrians were killed with the exception of the Targyrans. So I figured why not give you guys some food for thought and see what you think about it.
