Korea (Attack Machines)

Korea was reborn after 1947. Up until then there was a high concentration of people living in Jeju, believing that Kraventhorn would harm the peninsula. A few hundred lived there until they started to move towards the mainland. As of 2020, before the fall of civilization, they haven't reached Seoul.

International relations
While Korea was wary of the existence of rump governments across Japan, they were concerned about a hypothetical invasion of Korea by a potential unified Japanese state. Up until 2009, relations with Japan were constrained and the country remained in isolation. A memorandum of understanding forced Korea to join the reformed UN in 2009, set ties with Japan and rediscover the world, creating a quatrilateral agreement involving Korea, Japan, Taiwan and Singapore.
