My walkthrough: city - dungeon, partially - mines - second part of the dungeon. Next: I didn't dare to attack the monks, and as a result of intense mental activity, I figured out how to summon a ship. However, I still didn't have enough brains to reach the sword. So, later I gathered an army, defeated the monks, and captured the second city. I cleared the southeastern part of the map. I went into the dungeon, cleared it, and realized that it was a kind of hidden passage. Then I remembered that I hadn't reached the bridge that the Mage's Hut showed. I returned, received the quest about the bridge, calculated how much I would have to travel to complete it, gave up, and, after going through the dungeon and revealing the map with the cartographer, defeated the orc. That's it :)
Yes, out of all the quests, I only completed one, in which I had to bring mercury.
