The Slithering Pools is the name of the Abyssal realm once ruled, from his coral palace, by the now dead demon lord Ibdurengian, whom Aroden slew in this very realm. It was afterwards claimed by the balor lord Acizmun, the Boiling Tide, who thereafter began the process of preparing for ascension into a nascent demon lord while avoiding the notice of other Abyssal powers.
The Slithering Pools is a littoral realm abutting the Abyssal sea of Ishiar, complete with rock pools, which give the realm its name, and miles of sandy beaches overwashed regularly by the tides of that sea.
