Dagon is the demon lord of deformity, the sea, and sea monsters. He rules an Abyssal realm that consists of an immense ocean dotted above with strange and horrible islands and marked below with countless deep sea trenches and sunken cities. Dagon is 35 feet long, with the lower body of an eel, a horrific visage that evokes images of deep sea predators, and four long tentacles in place of arms.
