Eberron: Shadows of the Last War
One of the Five Nations of Khorvaire, Karrnath is a nation ruled by King Kaius III that is proud of its martial heritage and is the oldest of the Five Nations. It was founded by Karrn the Conqueror over two thousand years ago. The nation is particularly noted for its widespread use of undead troopers during the Last War and also the ruthless dictatorship of its monarch.
Lying in the northwest of Khorvaire, the nation of Karrnath stretches from Scions Sound in the west to the Ironroot Mountains in the east, and from Karrn Bay in the north to its tenuous border with the Talenta Plains to the south. It is a nation of equal parts open fields and dense forests with House Orien traderoads and Lightning Rail tracks providing ample travel considerations.
One of the oldest human nations on Khorvaire, Karrnath was built on a strong military tradition, one that carries on to this day. Karrnath supports a heavy middle class with plenty of trade businesses running in the large metropolitan centers throughout the western region of the country. Every Karrnathi citizen is forced into compulsory military service lasting at least two years. While many turn this service into a life-long career, others are quick to fulfill their duty and begin their actual lives. Most interesting about Karrnathi society is their use of the dead. There are no qualms about necromancy or undead in Karrnath and the forces of the military in the Last War were bolstered by skeleton and zombie forces. The summers are hot, short and wet while the winters are long, bitterly cold and full of snow. The people have grown hearty and robust out of this constant weather patterns.
