Skull & Shackles
Dagon (pronounced DAY-gon) is the Demon Lord of the Sea and Sea Monsters that dwell in its darkest depths. His symbol is an octopus eye surrounded by a gold disk inscribed with ancient looking runes.
Dagon is believed to be the largest of all the known demon lords. Dagon’s appearance is hideously monstrous and somewhat alien, being neither fully fish, eel, or octopus; he is some foul amalgamation of all three. His spawn often take after him, foul amalgamations of deep sea creatures.
Dagon is one of the oldest beings in the Abyss being one of the ancient Qlippoth, the creatures that dwelt in the abyss before demons. Dagon dwells in the depths of the Abyssal sea of Ishiar, in a sunken city known as Ugothanok a city with architecture so ancient as to be almost alien. Dagon is said to have slain the great kraken Kaktora, thereby creating the Devilfish now haunting Golarion’s oceans.
