Note: This mission becomes available after you have conquered the Nordberg town in Overlord 2.
Apparently, someone is trying to steal the Overlord’s ship. Travel to Nordhaven. You will see that the ship is trapped in ice. As you explore, you will run into some hunters, three flammable tar pit lakes and many gnomes. To melt the ice to get your ship out, look for a gnome in the middle of the tar pit. Target it and have your reds set him on fire. This will cause an explosion that will melt some of the ice.
When you run into the hunters, be sure to destroy their igloos. Beneath one of them is a turnstile. Have your minions activate it. This will pour some tar into a lake area. You will also run into some hunters who have a hidden turnstile switch in one of their igloos. Have your minions activate it, which then pours a large amount of tar into a lake area. After you set fire to three tar pits, you will encounter a small town.
There is a bit more ice to melt before you can get to your ship. Nearby is a large tar pit that will need to be set on fire. There are two ways to complete this task. Either find a way to do it yourself, or subdue 10 peasants with the Overlord’s magic to do it for you. Decide what to do and get that ice melted. Now, you can take control of the ship and sail towards Everlight.
This ends part three of the Overlord 2 walkthrough. Make sure that you check out the other parts of this Overlord 2 walkthrough so that you can learn how to get to this point in the game.
