To even access the rest of the Cloudy Stronghold, enter the Windy Archive and obtain the Black Flame. This will enable high elevation for the skyship. However, Imperial skyships are fiercely patrolling the Echoing Library and can shoot down your ship at a moment's notice. Fortunately, Kirjonen and Wiglaf have volunteered to assist in acting as decoys to allow an opportunity for your skyship to slip past enemy lines and reach the Library. Either one of them will intentionally draw the attention of one of the ships on the east or west, and while the distracted ship is in pursuit, pass through the opening towards the center of the region - but mind the Ancient Keepers circulating its perimeter.
