The most well known island in The Spice Isles is Cyn Dosa. The name of which literally translates into the common tongue as "Whore Island". Cyn Dosa houses the largest brothel in the world, as well as production of a potent and slightly hallucinogenic aphrodisiac known as Red Clover. What is less commonly known about the island is its massive cultivation of ginger root, for which they are the primary supplier of in Thisbē.

While the brothel property is not unlike a small city, the rest of the island is lush with tropical grasses and sapphire-colored sands. Access to the island used to be difficult in larger vessels due to the reef, but over time (and with many, many visitors), the channel passage has grown much more accommodating to the comings and goings of travelers.
