One day, the villager's protectors are routing bandits when the new Duke of Manster Raydrik attacks the village in search of Leif, kidnapping Leif's friends Nanna and Mareeta. Devastated by the town's destruction and his friends' abductions, Leif decides to face the forces of Thracia and retake Manster. Aided by Finn and a growing band of rebels, he rescues both Nanna and the enemy-controlled Mareeta, and defeating Raydrik's forces as they retake Manster and liberate northern Thracia. Leif's forces finally face Raydrik in battle, but upon his defeat he is transformed into an undead monster called Deadlord Mus. Leif destroys Mus, and cements his forces defending Manster and northern Thracia from the Grannvale army.
