Sundered from us by gulfs of time and stranger dimensions dreams the ancient world of Nehwon with its towers and skulls and jewels, its swords and sorceries. Nehwon's known realms crowd about the Inner Sea: northward the green-forested fierce Land of the Eight Cities, eastward the steppe-dwelling Mingol horsemen and the desert where caravans creep from the rich Eastern Lands and the River Tilth. But southward, linked to the desert only by the Sinking Land and further warded by the Great Dike and the Mountains of Hunger, are the rich grain fields and walled cities of Lankhmar, eldest and chiefest of Nehwon's lands. Dominating the Land of Lankhmar and crouching at the silty mouth of the River Hlal in a secure corner between the grain fields, the Great Salt Marsh, and the Inner Sea is the massive-walled and mazy-alleyed metropolis of Lankhmar, thick with thieves and shaven priests, lean-framed magicians and fat-bellied merchants—Lankhmar the Imperishable, the City of the Black Toga. (From "Induction" by Fritz Leiber) (Note: For real world size reference, the Island of Lankhmaria is roughly the size of South Korea)

The Forever Web

This web stretches throughout all of the world's key points and ley lines. Sometimes it passes through other dimensions and can even make a physical appearance in the material world. When the Forever Web is complete, the strands will activate, surging with energy, and entire worlds will each collapse into a singularity, ending it all. It is not clear what happens after that moment, but some believe that Atlach-Nacha will present the world as a new gem for the necklace of some supreme entity. Until the Forever Web is completed, no one can say except Atlach-Nacha. Fortunately, the Forever Web takes eons to spin, and individual strands can be attacked and cut without much trouble. Atlach-Nacha's webbing is only sticky where she chooses to make it so in order to tangle prey, for example, or to secure an attachment on the side of a precipice. Seeking to destroy the Forever Web, however, always runs the risk of drawing her personal attention.
