Gnomewarren lies some distance to the east of Fellgate, along the Cloud-Ankled Mountains. It is the largest gnomish settlement in the Settled Lands, a maze of burrows and tunnels carved into the peak of Mount Nhagar.

The gnomes are known to travel the tunnels and halls of the Old Dwarf Kingdom to Fellgate to trade. They are expert gem cutters and jewelers and their work is highly sought after across the Settled Lands. The routes they take through the mountains are ones largely unknown to the many tribes of goblins who inhabit the wider network of tunnels.

The gnomes of Gnomewarren enjoy good relations with their other neighbors, the giant owls of Mount Nhagar, to the extent that gnomes have been known to ride the owls into battle against a number of common external threats.
