The Dark Elf City of Hosuth (2001)

User Note: City campaign setting for any level characters.

From the introduction:

Hosuth is a campaign setting designed for characters of all races and classes, provided that they are open-minded and at least outwardly tolerant of slavery. The city itself is comprised of several different features: a swamp, mountains, hills, rivers, and lakes, and wilderness.

Despite its primitive appearance, Hosuth's unique climate allows for either straightforward, combat heavy adventures, or it can be a backdrop for complex political games. The dark elf rulers of the city are tolerant toward humans and other humanoids. They must be, or their city would die from lack of trade. The changes that the dark elf overlords forced upon the once-primitive city are drastic and require supplies of stone, lumber, grain, and other essentials. To this end, the city is open for trade.
