I confirm Pavel Dubrovin's victory.
That's exactly how it went.
I had built archers in the castle plus their external dwelling. In total, I gathered 27 crossbowmen by the first week. I decided to rush, seeing that there was an entrance to the underground. I thought that through it I would reach the opponent's respawn next week. So I headed there immediately, building a castle and the first four levels. It turned out that a long road awaited me, and I only reached the enemy's respawn by the end of the third week, after passing through two more. Well, naturally, my army was no longer up-to-date, although I was bringing reinforcements, even though Valessa looked decent stat-wise.
Thanks for the game.
