Stormheart Island

Stormheart Island is a treacherous island in the center of the Dragon Sea that is constantly surrounded by harsh weather known as the Eternal Storm. Not much is known about the inhabitants or if any still linger. Early efforts by the Alterian Empire to conquer the island were thwarted and the histories explain a fey-like people that lived there. 
The Stormheart causes issues for trade routes and for ships that attempt to sail across the Dragon Sea directly. Many sailors believe that the Onyx Basilica, the throne of power for the god Kernobosk, is on the island. Skilled navigators and seamen understand that the swirling spirals of the storm is what makes for quick travels from isle to isle.
Foolish adventurers who manage to gain a ship and the ability to steer her have made their way to Stormheart with hearts filled with desires for glory and heads filled with the dreams of greatness. Unto this day, no living soul has gone into the dense forests of Stormheart and returned. If it is true about the Alterian Empire's contact with them and their ability to push back a legion of the Empire, it's probably unwise to consider making the journey.
