Church of Dagon Bumper Sticker

The Esoteric Order of Dagon was the primary religion in Innsmouth after Marsh returned from the South Seas with the dark religion circa 1838. It quickly took root due to its promises of expensive gold artifacts and fish, which were desired by the primarily-fishing town. The central beings worshipped by the Order were the Father Dagon and Mother Hydra, and, to a lesser extent, Cthulhu. Dagon and Hydra were seen largely as intermediaries between the various gods, rather than as gods themselves. Even so, the cultists sacrificed various locals to the Deep Ones at specific times in exchange for a limitless supply of gold and fish.
