Fast roads lead to two portals. I break through one of them, there's a native secondary town. In the tavern, Gundula is found, the issue with the main hero is resolved. I capture the secondary town, and near it I discover two Griffin Conservatories and an external dwelling of nagas. I left all this for the second week. On the first week, I built nagas in the Citadel and golems in the secondary town.
On the second week, I continued to develop the secondary town, took two medusa hives, both level-2 Griffin Conservatories, the external dwelling of nagas. At the top of the secondary town area, I found another Griffin Conservatory. I also cleared a Pandora's Box granting 10k experience, a Crown +4, and a Breastplate +5. In the capital, I built a Castle, and in the secondary town - nagas.
I wanted to take the upper Griffin Conservatory with a scout hero, but I didn't dare because it's strong. It turned out to be a level-3 one. There are also several gold-generating buildings there. I visited the Library near the secondary town and prepared to move on.
On turn 141, I have 7 angels and 27 nagas, Gundula has Expert Air Magic, and I have Tactics and Logistics. I'm pondering where to go: into the treasure zone or to break through ГО. The opponent surrenders, sparing me from these painful deliberations.
