Mirabar is a wealthy mining city on the north bank of the River Mirar, on the northern Sword Coast. By the late 14th century DR it was the richest city north of Waterdeep, exporting metals, gemstones, and cut stone sourced from mines deep in the Spine of the World.

The city is home to a substantial population of shield dwarves who live and work underground alongside humans. True power lies with the Council of Sparkling Stones, a mixed dwarven-human elected assembly that sets production quotas, though the city is nominally ruled by a hereditary marchion.

Stone quarried in Mirabar is traded to Waterdeep via Luskan, and Mirabar-crafted goods are imported as far as Bryn Shander.
