Unicorn Empire

I've only completed the second mission so far. While it's still fresh in my mind, I want to ask some questions. The secondary objective states: "Don't encounter the dwarves, and you'll get a reward." Is there a way to modify this objective? In my opinion, it's impossible to complete. I tried to avoid the dwarves, but some of them were even afraid of my Waren and didn't come close. Then, a bearded man named Helmar arrived with his equally bearded companions and gave Andrew a beating right in Lake City. Andrew was just sitting quietly and didn't even look at their gathering from behind the city walls. I felt disheartened. I had to reload, regroup, equip Waren with all the best gear, and personally give Helmar a taste of his own medicine. After that, diplomacy was out of the question.
