Stormlanders

Located in the far west of the Island Sea, the Stormlanders live in a small series of Sky Islands that are constantly battered by storms. The harsh winds have cut them off of most of civilization, as only Thread Walkers dare to visit the islands, and even those rarely do so.
The Stormlanders have made do with their hostile environment. Most of their belongings are located underground, and they build sturdy constructions to prevent their farms from blowing away. They have little to no timber, due to the windy weather, making it incredibly hard for them to construct Sky Ships. Strangely enough, it doesn't appear that they consider themselves trapped.

But they will not explain their peculiarities, and have enough weapons around to counter any hostile acts with extreme violence. This, combined with the storms, have prevented their islands from being overmined for Cloudstone.
