Deep Waters Domain

Some deities dwell not in the heavens, but in the deep, dark recesses of the world, where life is absent but for a few resilient, incomprehensible beings. Some clerics draw their power from such deities, pledging their lives to the unfathomable powers of the ocean, vowing to become one with the eternal ebb and flow of the tides, protecting the deep seas and the many secrets contained therein.
