This is set around book 4 AFFC, where Euron has been elected king on the Seastone chair at the kingsmoot, Jon Snow has become lord commander of the night's watch.
Instead of reconvening at the House of Black and White for potential contracts, this family meet at the Isle of Faces to discuss their assassinations. It is said that crannogmen live on this island on the lake of God's Eye but it seems just to be the Faceless Family. Their hideout is inside the Weirwood.
Even though they consider themselves as 'no one', each have an item of memorabilia, whether it be jewellery, money or a weapon. This is for their identity to the family and their past life.
A letter from Cersei has been sent on from Kings Landing to Braavos, then to the family, concerning Lord Snow's assassination. She is willing to give up Tyrion as a sacrifice. Doran Martell sends demands for Sarella Sand to be assassinated, which he can pay for with his incomes. Also one mysterious man from Pyke wants Euron Greyjoy dead, and will give up his own life for it.
The Father, 44, (was known as Tyo Bereyn in Braavos): Assigned to the wall as a knight of Stannis Baratheons, called Edwyn Redsmeer, 40. He can also change into one of the black brothers if needs be. He always wears a emerald braavosi ring on his right hand.
The Mother, 39, (was known as Utta Bereyn in Braavos): Works in Kings Landing's kitchen as a cup bearer. Her name is Lyn, 26. She wears a necklace of sea stones and claims that it was her fathers who was a rich merchant. Lyn is able to send messages to the nobles of King's Landing, including Cersei, undetected.
The Bereyn Brothers (Sons of Tyo + Utta):
Kye Bereyn, 23.
Becomes an iron born on Great Wyk. His name is Quentyn Collark and serves under Victarion Greyjoy. He carries a Braavosi dirk, unbeknown to the other iron born. The eldest and most sly of all the Bereyn brothers.
Nevro Bereyn, 21
Becomes a Dornish sellsword in Oldtown. Known as Charmyle Garnell. Ordered to kill one of the sand snakes, Sarella. He always carries around braavosi dice to wager against anything other than death. This Bereyn brother is quick witted which is why it is said he has 'luck' on his side.
Cercello Bereyn, 20.
Perhaps the most swift and eager of the Bereyn brothers. His job is to carry messages to and from the family. This means his place is at Harrenhal, as Wes, a blacksmiths apprentice. He carries a hidden silver quill with him for writing the messages but there is also a deadly poison in the ink.
