The Cinnamon Wind is a Summer Islands swan ship captained by Quhuru Mo. Its home port is Tall Trees Town.
Quhuru Mo had sailed to Qarth where he encountered Daenerys Targaryen and her dragons. From there he was off to the traders' circle in the Jade Sea.
The Cinnamon Wind transported Samwell Tarly, Gilly and the corpse of Maester Aemon from Braavos to Oldtown. It was attacked by pirates off the Stepstones. The attack was beaten off.
Archmaester Marwyn intends to take the Cinnamon Wind to Meereen to serve Daenerys.
