"The Dreamlands is divided into four continental regions, each named for its cardinal direction.
The West is the most well-known region of the Dreamlands and is probably the most peopled as well. It is where dreamers emerge from the Steps of Deeper Slumber. The port of Dylath-Leen, the largest city of the Dreamlands, lies on its coast. The town of Ulthar, where no man may kill a cat, is also located here. Other important cities are Hlanith (a coastal jungle city) and Ilarnek (a desert trade capital). The land of Mnar and the ruins of Sarnath are found at the southern border. The Enchanted Wood of the Zoogs is also found here. It joins the South.
The South is the southern coastal region of the continent shared by the West along with the islands of the Southern Sea, including the isle of Oriab, the largest. The South's land-locked regions and its coastal areas are known as the Fantastic Realms, because they contain nightmarish and sometimes incomprehensible zones. Otherwise, the islands of the Southern Sea are fairly normal.
The East is a continent that is largely uninhabited, except for Ooth-Nargai. The city of Celephaïs is the capital of Ooth-Nargai and was created from whole cloth by its monarch King Kuranes, the greatest of all recorded dreamers. Beyond Ooth-Nargai are The Forbidden Lands, dangerous realms into which travel is interdicted.
The North is a cold, mountainous continent notorious for its Plateau of Leng, a violent region shared by man-eating spiders and satyr-like beings known as the "Men of Leng". The North also has a number of friendlier places, such as the city of Inganok, famous for its onyx quarries. The deepest reaches of the North are said to hold Unknown Kadath, the home of the Great Ones.
In addition to these regions, the Dreamlands has a few other locales that defy conventional description.
The Underworld is a subterranean region that runs beneath the whole of the Dreamlands. Its principle inhabitants are ghouls, who can physically enter the waking world through crypts. The Underworld is also home to the Gugs, monstrous giants banished from the surface for untold blasphemies. The Underworld's deepest realm is the Vale of Pnath, a dangerous lightless chasm inhabited by enormous unseen beasts called bholes. Bholes are likely the ancestors of the dholes of Yaddith.
The Moon has a parallel in the Dreamlands and is inhabited by the dreaded moon-beasts, amorphous frog-like creatures allied with Nyarlathotep. Interestingly, it is possible for a ship to sail off the edge of the Dreamlands and travel through space to the moon.”
