"The clans of gnomes in this mountain range are frequent visitors to the human city of Phent, which exists mainly to distribute tools, inventions, weapons, jewelry, and quality iron ingots the gnomes produce.  The mountain is populated by at least two copper dragons that engage in joke contests with the gnomes on an annual basis."1
