[TFCLS] The Faceless Men.

The Faceless Men are a guild of assassins based in the Free City of Braavos, though their members range far and wide across both Essos and Westeros. They command exorbitant fees, but have a reputation for success that is unparalleled by any comparable organization.

They consider themselves servants of the Many-Faced God, a god of death who is unknowingly worshipped by all religions in the world, in the form of one god or another. The weirwood Face for the Old Gods of the Forest and the Stranger of the Faith of the Seven are two such deities. Faceless Men are trained to relinquish their former identities and become "no one", which allows them to become entirely different people, all in service to the Many-Faced God. They also believe that, as servants of death, they must serve above all else and that they must deliver upon certain people the "gift" of death.

The Faceless Men possess the ability to physically change their faces, shapeshifting so that they appear as an entirely new person.

Their headquarters are located in the House of Black and White, a temple dedicated to the Many-Faced God.
