valar dohaeris

Valar Dohaeris is a High Valyrian phrase that means "all men must serve" or "all men must die". It is often used by characters in Game of Thrones to express their loyalty to the Faceless Men, the assassins' god. The phrase is first uttered by Melisandre and Grey Worm at Winterfell, and later by Arya and Missandei in Braavos. pik88
