Campaign 2, mission 4: "Beasts and Bones"
Tell me how to form an alliance with the orcs. There, where Arantir says that it's not necessary to fight them, and according to the books, they are brave and strong.

In the upper left corner, there will be a blue castle. Inside the castle is an orc hero with an army. After leveling up and gathering an army, go to him. When you arrive, there will be a cutscene where the orcs appoint Arantir as their leader. Defeat this hero and his army, and there will be another cutscene, this time with the shaman, where she promises peace, friendship, chewing gum, and roller skates as a bonus. In fact, the mission ends here because the main goal is to find the path to Holyfire, which passes right above this castle. But there's one question: why form an alliance if orcs are not needed in the last mission, and Arantir doesn't appear in later campaigns.
