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)

Little Grey Mouse

"Oh, the whiskey was spilled on the barroom floor
And the bar was closed for the night
When out from his hole crept a little grey mouse
To dance
in the pale moonlight.
He lapped up the whiskey on the barroom floor,
And back on his haunches he sat,
And all night long you could hear him roar,
BRING ON THE GODDAMNED CAT!"
