Hello, author. I just finished playing your map. The scenario was really good! It was interesting and not monotonous. I'm playing on the easiest difficulty level because I just started playing Heroes. I just didn't understand the ending: first, I chose to "spare the traitor," and on the way home, I was killed by the Archangel. I replayed, and after the battle, the game simply told me that my heroes were dead and it was game over... What did I do wrong?
For a good ending, you need to execute the traitor and own all three blue cities.

Nice answer. Someone asked that a year ago. Oh, what nostalgia, my old good maps for Heroes 5. And then I got hooked on Disciples and moved on.
