Untergarten in the subterranean breadbasket of the city of mists. As the city grew, citizens built ever upwards to escape the annual floods. Eventually the entirety of Untergarten was eclipsed by the ever growing city. Now sunlight must be piped downwards from Highhill far above via light conducting ores brought up from the depths bellow.
the Untergarten produces much of the agriculture products that feed the city above. Once each year the Weaping river bursts its banks and floods the Untergarten.
