To win, you must capture all enemy towns and castles and defeat all enemy heroes. Some Border Guards can only be passed if a Hero carries a Quest Artifact from a previous scenario, but the reward is great indeed.
Necropolis male narrator: Erathia's military lies before us. It is time to make a bold strike. King Gryphonheart has trained their generals and knows their tactics. Morale will decide this battle. Morale is not a factor for the undead. Once we fill our ranks with their dead, our horde will grow and their morale will falter. Then we will swarm over them. Soon King Gryphonheart will rule Erathia once again.

You received your orders personally from King Gryphonheart. You will launch your attack from three fortresses along the Erathian border. Resistance should be light at first, but you must secure the area quickly before their reinforcements arrive.
Day 1 - Intro part 2
It is clear that King Gryphonheart wishes to return to the Throne of Erathia, but this time he wishes to do it as a conqueror. You can smell the scent of lives waiting to be harvested even from here. Go now, the time has come.
