Leviathan

A terrifying apex predator native to Paperweight, the leviathan is the name given to a dangerous species of aquatic megafauna, with a fierce reptilian head full of long and viciously sharp teeth, and several huge prehensile tentacles. Though leviathans tend to avoid interactions with the surface unless provoked, they remain an ever-present dread within the nightmares of Paperweight's anglers, who tell and retell stories about these terrifying animals.
