"There is only one god, and His name is Death. And there is only one thing we say to Death: 'not today'."
―Syrio to Arya Stark.

First Sword Syrio Forel was a bravo dancing master and the First Sword to the Sealord of Braavos. Formerly the First Sword to the Sealord of Braavos, Syrio was hired by Eddard Stark to train his daughter, Arya, how to use her sword Needle, feeling her weapon would be suited to Braavosi water dancing. Syrio teaches Arya alot of what she knows, largely in regards to her swordsmanship. During the Lannister purge of Eddard Stark's household guard, Ser Meryn Trant of the Kingsguard leads several guardsman to capture Arya, only for Syrio to battle them while she escapes. His fate is ultimately unknown, but its largely accepted that he was slain in combat with Ser Meryn.
