First Sword of Braavos

First Sword of Braavos is the title held by the chief protector and champion of the Sealord of the Free City of Braavos.

For nine years Syrio Forel held the position.

In the books
In the A Song of Ice and Fire books, the First Sword of Braavos is chosen by the Sealord often because he is the most observant of the Bravos, not necessarily the most talented swordsman, thus most able to protect him from threats both seen and unseen.
