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)

Emeric Rūhn

The founder of the royal line, Emeric Rūhn, was a charismatic leader and a skilled negotiator who managed to forge an alliance with the influential Guild of Mages and the revered Order of the Sentinel Knights. With this formidable backing, Emeric Rūhn orchestrated a peaceful coup, outmaneuvering his rivals not through force but through a series of strategic marriages, promises of reform, and political maneuvering that secured him the crown. The early rule of the House of Rūhn was defined by Emeric's vision of a centralized power that could bring stability to a fractured kingdom. His establishment of a codified system of laws and the creation of a council of advisors drawn from various sectors of society were revolutionary at the time and laid the groundwork for sustained governance.
