It went well, and I had fun. First, I left Fedya in the Castle for the missions, and sent Ossir out to explore; he had archers, dendroids, and some other units he had acquired. While Deidra was holding her position, I moved to another island and cleared out everything up to the garrisons (to prevent any glitches). After building up my Castles and buying a good army, I headed towards Deidra. I thought, "Okay, now they'll be coming after me." But after defeating her, the purple faction didn't bother me, even though they were clustered near the portal. Then, the turquoise faction decided to pay me a visit. But the threat level for Ossir was only medium. I quickly gathered an army for him, and the threat level dropped to low. Zoltan, the blue player, visited the mercury and gold mines, as well as the lighthouse, and then headed back to his base. After waiting for him to pass the second garrison, which I could still see on the map, I went to swap Ossir for Fedya. I still haven't found any light magic for Fedya, and this is annoying; I wish I had an enchanted arrow with divine retribution... the enemies would be terrified. I swapped Fedya so I could start developing him, and Ossir, thanks to my favorite education strategy, reached level 12. I thought that since I had swapped armies in Talla, the purple faction would start attacking me, but that didn't happen either. I decisively finished off the garrisons with Fedya, freed Tolya from prison, and killed the blue player, and then I waited for the right moment to end the mission. I didn't specifically recruit any garrison units. Tolya went to the green Castle, and I freed Ryzhaya in the meantime; she also cleared out some Castles. And only then did I buy troops for the garrison.
The end)))
