Character from A Song of Ice and Fire by George R.R. Martin
A Faceless Man from Braavos who changes faces like other men change clothes. 'A man has no name.' Trained Arya Stark in the arts of assassination at the House of Black and White.
Jaqen first appeared as a prisoner in a cage, with red-and-white hair and a foreign accent, speaking about himself in the third person. He offered Arya three deaths as payment for saving his life, then vanished — literally changing his face in front of her. He reappeared at the House of Black and White in Braavos, where he trained Arya in the Faceless Men's arts: poisons, disguise, combat, and the philosophy of the Many-Faced God. He is calm, enigmatic, and possibly not a single person at all. 'A man' is a role, not an identity — and that's the lesson he tried to teach Arya.
A slender, elegant man who changes faces as others change clothes. In his most familiar guise: a handsome face divided by a streak of white through red hair, with warm dark eyes and a knowing half-smile. Dressed in simple, nondescript clothing that draws no attention. Moves with fluid, silent grace, his true identity as unknowable as his order demands.
