The phrase is a part of a strong theme speckled throughout HBO's fourth season, which started airing in March. As Arya Stark sets out to avenge those who have fallen, she adopts it as a mantra against the people she wants dead. The label art features a two-headed coin, which was given to Arya by Jagen H'ghar, one of the "Faceless Men of Braavos" assassins who can change their appearance on demand. Each cork is fire-branded with "Valar Dohaeris," the traditional response phrase to "Valar Morghulis" meaning "all men must die."
