This is the story of Elegist, an explorer, a wanderer, a poet, a sea (sorry, "zee") captain, a lost soul. Elegist comes from Fallen London — that's alternate-history Victorian-era London after the bats came and forced the people to descend beneath the surface. Elegist is too young to remember the world from before, but just the right age to know all about it. He mourns for the old London, the past before the shadows. Now he looks for hope in the vast sunless seas before him.
