Jaqen H'ghar. He's an assassin.

Jaqen H'ghar was part of Yoren's group of recruits taken from King's Landing to join the Night's Watch, just after the execution of Eddard Stark.[2] He was one of three prisoners found in the infamous "black cells", the dungeons reserved for only the worst criminals. The other black cells criminals, Rorge and Biter, were afraid of him.[3] Jaqen behaved in an obsequious manner toward Arya Stark while being escorted to the Wall. When Ser Amory Lorch attacked the company, Arya saved him and his two fellow prisoners from death by a fire.[4] At Harrenhal, Jaqen found her again and told her that she is owed three deaths and to select three people for him to kill, to repay the deaths she stole from the "Red God". Arya used him to eliminate two of her enemies at Harrenhal, but he pitilessly rejected her request for aid in any other way. By threatening to select Jaqen himself as her third choice, Arya ultimately forced him to help free the Northmen imprisoned at Harrenhal.[1]

Once his debt was filled, Jaqen prepared to take his leave, but first gave Arya an old iron coin and instructed her to give it to any man of Braavos saying the words "valar morghulis" should she ever need more help. Then he announced that "Jaqen H'ghar" must die, and passed a hand over his face. His entire face magically reshaped into that of a hook-nosed man with a gold tooth.[1]
