Anango Island:   A large island not far from Schendi. It is similar in some respects to 18th century Jamaica on Earth. Reputed to be the home of mythical "black wizards" though in actuality there is no magic on Gor.

Also known as exchange islands, they are administered as Free Ports by the Merchants. Included are Teletus, Tabor, and Scagnar. Others were Farnacium, Hulneth and Asperiche. In the south are Anango and Ianda, and in the far north, Hunger and Skjern, west of Torvaldsland. These islands, and free ports on the coast such as Lydius and Helmutsport, Schendi and Bazi make possible the commerce between Cos and Tyros and cities of the mainland.
(Book 6: Raiders of Gor, page 137)

"The magicians of Anango are famed on Gor. If you wish to have someone turned into a turtle or something, those are the fellows to see. To be sure, their work does not come cheap. The only folks who are not familiar with them, as far as I know, are the chaps from far-off Anango, who have never heard of them."
---Magicians of Gor, page 259

Anango Island: This is an exchange island, a free port administered by members of the Merchant Caste; they speak Gorean. It is located very far south of the equator, almost at the edge of explored Gor. The jungles of its interior serve as the setting for many fanciful stories of strange races, mysterious plants and fabulous animals.

The "magicians of Anango" are well known everywhere except on Anango. They speak Gorean.
