Korshan

The ancient hill town capital of the kingdom of Ruhal. Historically unbreachable atop its steep cliff above a winding river and protected by a wall seven gates thick, its brooding castle sits atop the ruins of a nameless but much more technically advanced castle, its underground still intact, with carved passages and high-ceilinged, well-ventilated meeting halls within the castle hill.

From Orland of Nef:

"I quickly learned to lie about where I was from. I made up many answers: from the outer islands, I said, grinning. Or from the mainland, or from the East; anywhere but from my beloved Korshan, in Ruhal, with its sweet air full of chestnuts and acorns, with its giant maple trees atop our ancient town walls, ringing the city in fragrant green throughout the summer, blazing fire-red and yellow leaves every autumn before the frost...."
