Outer Longzhou is one of the southernmost states of the Eastern Country, named for its resemblance to a dragon cradling the moon.
Longyue Island, also known as Longyue City, is the state capital, the "moon" in the "dragon cradling the moon," and also the largest naval base and shipbuilding center in the Eastern Country.
Institutions like the Church of the Lady of the Forest, of such rank, have branches across the nation (the Sixth-order peak that Lu Ping'an killed was a former high-level member of Changping Church), yet their core power still leans towards the central and southern regions.
Longyue Island, due to its natural subtropical climate (the superficial reason), and a certain distance from the mainland conducive to development (which also facilitates all kinds of over-the-line experiments, the unspoken main reason), is one of the most important operational sites for Lin Nu's Church in the south.
