Question: asoiaf who is the alchemist?
Answer: The alchemist is a young man with a hooked nose and thick, black, curly hair. He has the shadow of a beard and there is a faint scar on his right cheek. This is an identical description to the appearance assumed by the Faceless Man assassin known to Arya Stark as Jaqen H'ghar during the fall of Harrenhal.
