Uninvited guests.

I won the map playing as Demons on "Veteran" difficulty, in 160 days. The starting conditions were exceptionally favorable. The tavern offered Daleb and Jezebeth, so I decided to start by developing Kahn, but even then, things didn't go smoothly, although it was somewhat better than starting on "Hero" difficulty. I retreated and made Daleb my main hero. Since resources were better, the Castle developed steadily for a while. Problems started with the Magic Tower, where, out of all the "Darkness" spells, only "Vampirism" was offered. The mages and the Utopia also didn't offer anything useful. Building dwellings of levels 5-7 took a long time. I should say that the "Witch Gathering" event on "Veteran" isn't very scary. The first strike still has consequences, but the others are barely noticeable. Daleb easily repelled the attacks while staying behind the Castle walls, but in the field, she was overwhelmed. The game became almost static; my main hero from the Castle could only move within a two-day range. I was forced to develop Kahn. With Daleb's broad back protecting him, he thrived. The AI didn't bother him, he could move around the entire map, and he leveled up to 20. Unexpectedly, he managed to break through the gates and capture the enemy Demon Castle. From that point on, the process went quickly. Finally, Kahn captured the Necromancer's Castle. In conclusion, a few words about the unconventional Demon hero. Kahn is quite weak up to level 15. At a higher level, he is still weak, but a large army helps to mask these shortcomings. All his upgrades are in attack. At level 20, his defense was -1, magic was -2, and knowledge was 5. If it weren't for the added artifacts, his magic would be useless. Moreover, the special ability, which activates before the start of the battle, pushes him to the end of the initiative order, and even "Sharp Mind" doesn't help. Due to the random selection of the target and the type of spell, the battle almost always starts badly.
