Parental Guidance in Heroes 4

Your father, King Tearix, appoints you to serve as the commander of his military. While this gesture seems to exhibit a great confidence in your abilities, the truth is your father absolutely abhors failure, especially from his own blood. So, to test your skills, he orders you to infiltrate the southern realm of Vraal the Unholy and bring an end to this vile necromancer within 120 days.
