Oldpassage

Oldpassage (originally Adstunad) is the name of both a province in Esmaria as well as a set of ancient underground dwarven tunnels under the Havoral Divide that link Esmaria to the Forlorn Vale. It started as a dwarven mining colony under the authority of Castanor but was eventually expanded into a tunnel, allegedly as a larger dwarven initiative to persuade the empire to allow further dwarven colonies along the Havoral Divide mountains, giving origin to places like modern-day Silverforge.
