The origins of this fortress are a mystery. It appears to be of Isparian Construction but no one is sure who built it. One theory is that some faction of the Aluvians built the structure. However they discovered to their dismay that it was built atop some ancient Empyrean ruins. Shortly after it reached its current stage of construction undead began to appear in the fortress` cellars and harrass the trespassers, eventually driving them out. At some point after that, a tribe of banderlings took up residence, thus making this one of the few locations where a banderling chief can be found. It`s assumed that while the zombies found here harass the banderling ravers, breeders, and raiders within and scouts and guards without, the banderlings pay them no mind, being content to just leave the cellars of the fort to the undead.
