On the northernmost tip of the eastern continent (Essos), lies Braavos, arguably the most powerful of the nine Free Cities. Braavos is ruled by the Sealord, and has close ties to Pentos, one of the other Free Cities located further south on the western coastline of the continent. Braavos consists of approximately a hundred or so islands, separated by water, and linked together by bridges. They are a seafaring people, and their warriors, called bravos, are famous for their unique style of swordsmanship, known as Water Dancing. The style eschews armor, and makes use of slim, narrow blades; it also focuses more on precise footwork and agility rather than hacking and slashing. This style probably arose because of the danger of wearing armor onboard a ship.
