The Drowned God

The Drowned God is a ancient God that was once worshiped by sea-faring people across the world. Those blessed by the Drowned God gained its protection from all manner of creatures. Millennia ago the AnglerFolk clashed with the worshipers of the Drowned God, pitching the Drowned God and its servants against The Leviathan and its servants. The conflict sent tidal waves crashing across the globe destroying many coastal settlements. It ultimately ended with the Drowned God being dragged down into the infernal abyss beneath the strength of the Leviathan. This scattered its followers who all fragmented and fought with each other over what was left after the war. It's following is still around today though in much smaller numbers which many different traditions. Some perform active sacrifices to the Drowned God others sacrifice the souls of their defeated enemies to it by throwing them into the abyss. There have been stirrings from the deep, old bonds grow week, and what is dead may never die, but rises harder and stronger. The Drowned God's animal is the Lusca it has a megaldon's front half and razor sharp tentacle's for the back half. Dragon Turtle's are also worshipers of the Drowned God.
