Korhal IV (often simply refered to as Korhal) is the fourth planet of the Korhal System in the heart of the Koprulu Sector. Formerly a temperate world with at least two large oceans, it was turned into a nuclear wasteland by a nuclear bombardment. During the four years since the establishment of the Terran Dominion, a large portion of the planet has developed into an ecumenopolis. Korhal had a dense atmosphere and used to be a lush, temperate and warm world before its destruction, possessing distinct seasons such as autumn, balmy summers and mild winters. The planet orbits a single star.
