Jaqen H’ghar is a mysterious man who says he belongs to the brotherhood of Faceless Men of Braavos. Jaqen is being transported as a prisoner to the Wall in the same group as Arya. When his carriage cell is lit on fire, he pleads with Arya to set them free, and she does, saving his life and two others. Jaqen tells Arya that he owes the Red God three deaths for the three lives she saved that were certain to die. Arya tells him three names and he mysteriously assasinates all three men. Before being on his way, Jaqen gives Arya a Braavosi coin and tells her that if the time should ever come when she needs him, simply give this coin to any man from Braavos and say the words “valar morghulis,” meaning “all men must die.” Before leaving, Jaqen states that Jaqen H’ghar is now dead, before passing his hand across his face and appearing with an entirely new face. In the finale of season 4, Arya uses the coin Jaqen gave her to board a Braavosi ship headed towards Braavos.
