Kernow is the smallest of the four nations occupying the British Isle. Kernow is bounded by Atlantic Ocean on the north and west, by the Mare Britannicum on the south, and the nation of Britannia on the east. A peninsula, Kernow has two distinctive natural landmarks. At the southwest point of the nation is the cape of Land's End, which is the westernmost point of the British Isle; at the southeast tip is Lizard point, the most southerly extension of the Island. The Scilly Isles, also a part of Kernow, are situated about 25 miles southwest of the cape. Sailors generally avoid the Scilly Islands as they are said to be haunted by evil creatures. Most of Kernow, especially in the east, is high, wind swept moorland, which decreases in elevation toward the west. The deeply indented coasts of Kernow, with their fine harbors, are lined with rocky cliffs. Fertile valleys make up the southwest and central part of the country. The principal river, the Tamar, forms most of the boundary between Kernow and Britannia. The two largest cities in Kernow are the port city of Penzance and the capital of Exeter. Kernow is also rich in tin and lead deposits and its mines supply a great deal of Keltia's needs for these materials.
The people of Kernow are a hardy and rugged people who resisted being Romanized during the Roman occupation. The Kernowens are a hardy breed of Celtic people who are renowned for their shipbuilding and their reputation as sailors and navigators. Kernow has a strong national Navy and its forces comprise a large portion of the Keltic Navy. The Penzance shipyards build most of the Warships for Keltia's Navy.
