I'm afraid the jury's still out on that one.
A small group of islands off the coast of Storm, the western half of Valisthea's twin realms. Here the Crystalline Orthodox, an extreme faith that worships crystals, reigns supreme. The Iron Kingdom controls Drake's Breath, the Mothercrystal that sits at the heart of one of their islands—long a source of contention with neighboring Rosaria. Isolated and aloof from the mainland nations, the Ironblood speak their own language. Orthodox doctrine judges Dominants to be unholy abominations, and any unlucky enough to be born on the islands are executed.Official description
