The City-State of Sandfell is a mecca for trade that precariously hangs in the balance between two of its mighty trading partners. The City clings to the shores of the Island that boasts the same name. In this City resides a self-suffient orphan boy by the name of Bryant. Bryant lives on his own and survives day to day by dodging neighborhood street gangs and Watch Officers that roam the cities mean streets. In a desperate bid to raise some much needed coin he takes a forbidden trip into the deadly jungle that surrounds the city. After a very close run in with the creatures that stalk the sweltering jungle he finds Marta. She is a young unbounded Waverunner, which is a legendary living ship. Marta shipwrecked on the shores of the stream for countless years chooses Bryant as her Captain. The choosing is a lifelong commitment that bonds the two and heightens both of their senses. As they explore their newfound abilities they battle a fleet of deadly warriors, and monsters of the deep, all before finding a safe haven.
