"Flight to Salvation" - "Summoning the Dragon" [Campaign 4, Mission 3]

I want to warn those who are playing this mission. Yesterday, my Zephyr descended into the Dungeon again to deliver the last artifact from the Dwarven set to Wolfstone and retrieve the Tear of Ashi. He couldn't make it back to the surface. They say the passage is blocked. Luckily, I had a save before entering the Dungeon. I loaded it, went down, and immediately exited without any problems. You should save before entering the Dungeon. I'll experiment with this a bit, and then I'll start the mission again because I spent too much time looking for a place to settle the city and wasted a lot of valuable experience summoning unnecessary Rakshasas. Zephyr, even without them, with his starting army, easily defeats all the neutral creatures near the exit of the Dungeon without any losses. And I didn't immediately figure out how to develop Wolfstone. I'll leave the second city unguarded. Let them capture it. Otherwise, nothing works because the enemies instantly flee the battlefield. But they won't be able to escape from the city. I reread my own posts on this page. Back then, I was playing as a Warrior. Now I'm playing as a hero in version 3.1. I had already forgotten everything. I only remembered that the city is settled somewhere near the exit of the Dungeon, but I went in a completely different direction. Zephyr doesn't need Dwarven troops to clear out the neutral creatures.
