This remote island is, as most islands in the archipelago, tall and rocky. There are ample forests. The Wingmaidens' village is built of raised, some-like structures above the trees, almost like tree houses.
About a thousand years before the events of "Snotlout's Angels", Razorwhips nearly went extinct because male Razorwhips continually killed the offspring of rival dragons. So the Wingmaidens vowed to help the species out, offering to care for the hatchlings on their island and help defend them from any male presence. The dragons then made the island their home, including their nesting grounds. It's revealed that Windshear was once one of the Razorwhips they had cared for before Heather found her.
In the episode, "Snotlout's Angels", Snotlout was brought to Wingmaiden Island after he fell into the sea and the Wingmaidens rescued him. While searching for him, Astrid, Ruff, and Heather are warmly taken in by the natives, where they are offered rest, a warm meal, and entertainment; specifically boar wrestling. The natives explain that they aid Razorwhip mothers care for their young and defend against males who might try to harm them. Because of this, there are no males allowed on the island for their own safety and the well being of the dragons.
