In the name of Dagon!

The Esoteric Order of Dagon is a cult founded by Captain Obed Marsh in Innsmouth using the practices learned from the inhabitants of a Polynesian island. The people of Innsmouth carried out ritual sacrifices on Devil's Reef to appease the Deep Ones. In 1846 during one of these sacrifices Captain Marsh and several members of the Order of Dagon were arrested, though no formal charges were made. It was disbanded when the U.S. goverment launched an attack on the town in 1928 (HPL: The Shadow Over Innsmouth).

The Esoteric Order of Dagon is an organization controlled by the Deep Ones and their human/Deep One hybrids. Prior to the 21st Century, they spread their influence across the world and recruited humans. Their ultimate objective is to free Cthulhu from his imprisonment, and therefore are searching for R'lyeh. Meanwhile they breed with willing cultists or unwilling captured humans in rape camps (mostly the latter) to increase their numbers. At their disposal are mecha, the Star-Spawn of Cthulhu, monsters of the deep, and servitors of Cthulhu. They control the oceans and most of the coastal regions of the world, having complete naval supremacy.
