Yan'Shari

Yan'Shari, formally known as the Free City of Yan'Shari, is a drow elf settlement in the Middle Layer of the Rishan Underdark. Founded as a forward base by the Eternal Drow Empire during the Shadow Age, Yan'Shari's original purpose was to strike out at the more populous of the Nine Great Dwarven Cities. Following the drow's routing after the Battle of the Rising Sun on the surface, Yan'Shari was cut off from the empire by a united dwarven-gnomish coalition. Though it was a major thorn in the side of the Nine Cities and the Gnomish Freeholds, its location was kept secret from its founding until the end of the Burning Age.
