Shadowsea

Dagon's realm, known as Shadowsea, is the 89th layer of The Abyss. Shadowsea is an underwater realm with a seabed dotted with ruined cities, but without a surface. At certain points, if one ascends or swims upward, he will find himself surfacing on the 88th layer, which is the Gaping Maw of Demogorgon.
The deepest trenches and chasms of Demogorgon's Gaping Maw lead to an ocean below the ocean, a lightless realm of horror called the Shadowsea, domain of Dagon, Prince of the Darkened Depths. Long has the reclusive obyrith lord dwelled in this nigh-inaccessible nethermere, growing fat on the tribute of quivering demons who visit to learn the secrets of the ancient Abyss.
Dagon's amorphous palace grows from the ocean floor, a looming edifice of slimy mud cut through with colonies of immense sea worms and crawling with blind, phosphorescent skitterers. Wastriliths pose a significant danger. As Dagon's favored servitors, they enjoy free reign of the layer, so long as their predations do not befoul the demon lord's inscrutable plots. Even the rare skulvyn or myrmyxicus take pause before braving the Shadowsea, for rumors persist of giant clouds of cloying pollution neither wholly alive nor dead that strip the flesh from those who fall within their discolored expanse.
