Skies of Arcadia
Spanning and blocking the single valley allowing access to the capital city is the Valuan Grand Fortress. It is a massive metal construct that stretches across the entire valley from side to side and from the boundaries of lower-sky to the cloud-ceiling. It is said to extend down the valley a half-mile thick. It is the largest, most advanced structure of the new world, and is widely recognized to an engineering marvel equal to the feats of the Old World. It is the only modern structure to be afforded such an accolade. It is clearly not without merit, as it survived a 3-day bombardment by the entire Nasr Navy during the Valua-Nasr War 20 years ago with no more than superficial damage.
