The 33rd Commander of North Ocean Principality who successfully resisted the invasion of Northern Tribe. The North Ocean Principality was established to strengthen the frontiers and resist the invasion of Northern Tribes. In the Principality year 103, the Northern Tribes came again. At that time, a young general named Ludwig took up the Frostwolf Sword, a sword representing the supreme power of the Principality. He led troops to cut enemy's supply lines and recapture several key strongholds. Ludwig also reversed the long-standing defensive strategy and launched a war on Northern Tribes, known as the Northland War. With years of combat experience and knowledge of the Northern Tribes, Ludwig led army to penetrate deeply into the Northern Tribes, destroying their court, killing and capturing countless tribal soldiers. The Northern Tribes have no longer been able to invade the south. Ludwig the North Frostwolf successfully defended the frontiers of empire with his great military ability and became a role model of all imperial soldiers.
