The Hero's Path

I never thought I would find something like this in Heroes. Huge thanks to the author for their hard work and patience. It's great when you can calmly explore the map, and it's even better that the author made this map for everyone. You can either wait until you have a substantial amount of gold in your bank to buy a large army, or you can fight with a smaller force. I started playing the map only yesterday, but all this time I had one thought: this is the kind of game I want to see in the 8th installment. Of course, I understand that this isn't exactly Heroes, but I agree that it's nice to have many tasks on the map, and not just build a castle and defeat the bad guys. I wish the author success and new ideas. I have a couple of questions about the map. First, is it possible to learn "Resurrection" anywhere? And second, what are those huge armies that appear on the road?
