Cult of Dagon

The surface of Ishiar is inhabited by fiendish and half-fiend humans known as Ishians, who seek to impress Dagon by constantly fighting each other and by claiming new islands in his name.^[5]

Dagon is quite active on the Material Plane, regularly sending his demonic minions to the deep oceans of the world to become high priests for evil aquatic monster races,^[1] such as the gutaki. He is even worshiped by some of the more savage sahuagin tribes.

Unfortunately, Dagon's foul influence is not limited to the ocean depths; he is also revered by some debased coastline societies, who often maintain a façade of worshipping another deity. In these twisted communities, land dwellers mix with ichthyic beings from the depths, spawning horrible cross-breeds which have no place in the natural order of things. Marsh giants are normally the most fervent of Dagon's land-based followers, but his cult has been growing amongst humans in isolated villages, who secretly turn to his worship, sometimes on the promise of bountiful fishing or alien golden jewellery.^[4][7][1][5]

Some sailors worship Dagon, luring ships to collide with rocky shores and performing blood sacrifices to call forth sea monsters.^[9]

Dagon is one of the three demon lords primarily worshiped by the Bekyar people of the Mwangi Expanse.^[10]

Some of Dagon's followers (particularly deep ones) also worship the Great Old Ones, most often Cthulhu, mixing the traditions of both into a single blasphemous religion. Some elder deep ones take his name for themselves, which Dagon sees as a compliment.^[5]
