The Dominion State of Yimmen is the site of one of the earliest civilizations on Koneg. After first landing on the southern shores of modern Lemin some of the people migrated across the strait to this larger island, where they stayed for over a century before expanding down into the mainland west of where is now Sanzoriland.
Yimmen is a major exporter of precious metals. As such, is has grown to prominence in the global markets exporting gold, copper and lithium in large quantities.
