The Krakeneers are the lifeblood of Vralkast, possibly the most important group to the continued survival of the city, even if they aren't the most powerful. Vralkast relies on the bounty of the Sea of Sorrow to survive, and its the Krakeneers who go about the business of extracting it. They hunt the leviathans that call the sea home, hauling them back to Sowshore where they are butchered for meat and bone, feeding and supplying the people. Nothing goes to waste, the bones are used in construction, the crafting of tools and equipment, art, and even currency.
You can always spot an experienced Krakeneer, their time on the serpentkeels changes them. They grow mutations, many have gills they don't remember growing, and they get restless when forced to return to land. The sea calls, and it is they who must answer.
