World of Gaus
The smallest and most furtive of the Thaigs is the city of Gauldrokan, fourth to rise. It is a hub of raw magic, powered by huge arcane engines, which absorb and transmute the stray magical energies flowing and wafting throughout the world. The air, the weather, the moons and stars — even life itself powers this fantastic colossal. In truth, how exactly these mystic engines function is a bit of a mystery, lost upon not only foreign scholars, but also the native dwarves. The engines are self-sustaining, meaning they not only maintain themselves, but also upgrade functions interpreted as obsolete. After thousands of years of this, their precise interworkings have become so advanced they are now completely alien to those that built them. Insight into the issue might be gleaned from the original blueprints, but they were unfortunately lost eons ago to the fires of a great civil war. The dwarves just accept it on good faith that these puppies will keep on going for forever.
Gauldrokan is forbidden to any outsiders; indeed, the place is so private they’re even wary of returning Blackfeet, elsewhere so vital to dwarven ways of life. They are insular and enigmatic, preferring to stay within their safe walls and pontificate about the mysteries of the universe. Their extreme prowess in the ways of enchantment and magic has allowed them this isolation: thanks to their magically automated factories, dwarves of Gauldrokan are provided everything they could ever want, making trade essentially moot and defunct. What the city looks like inside is a complete unknown, but outside it is a bizarre patchwork of buildings, towers, walls, domes and shields, all stitched together by magic and carried about on four enormous spindly legs. Huge steaming clouds of magical byproduct billow from crooked smokestacks, leaving a clear trail for any looking to find the city – but just know, those who wander too close have been known to meet strange and terrible fates.
