From the back of the book: The waters of Vylbrand have always been perilous, ever more so since, after the Calamity, the lighthouse of Pharos Sirius has gone dim. Despite their best efforts Naldiq & Vymelli's, Limsa Lominsa's renowned ironworks, have only failed over the years to reclaim their insular guide, due to the ferocious wildlife and the noxious aether permeating the building. But as words have it a lalafellin scholar of incredible talent has recently joined their efforts, with an invention that might turn the tides for the better. Now they only need a team of talented adventurers to secure the area and restore a safe route towards the shores of Limsa Lominsa.
