Mountain Watching Fortress, also known as Pandora Fortress, is a strategic outpost in the northern part of the Falar Empire. back in the early days of the Fourth Epoch, when the Yarran Continent was still plagued by war, the Falar Empire did not yet exist. At that time, the southern part of the Pandora Mountains was ruled by several small kingdoms that frequently waged war against each other, with their territories changing hands almost yearly. However, no matter who occupied the lands at the foot of the Pandora Mountains, they all shared a genuine fear of their mysterious and powerful neighbor. To defend against the hypothetical threat of Butte mages descending from the Pandora Mountains to invade their lands, these small kingdoms set aside their animosities and jointly constructed a fortress on the only pass down from the Butte Plateau, naming it the Mountain Watching Fortress.
