In the end, I captured a secondary Castle, found another Conservatory. And at that time Torosar unexpectedly appeared, having broken through the adjacent zone, one day's march from my main. The chain was slightly short of delivering meat from the Castle, and I couldn't break Tanth. Thought for a long time and at the last second planted a Castle and bought single units. This could have been a fatal mistake, since against 3 Towers I wouldn't have gotten my main back. But the opponent miraculously skipped past Rampart and ran towards the Castle. Later he said he didn't notice my main. On the Castle zone, the first skirmish between Tanth and Torosar occurred, where I drove the opponent off with almost no losses thanks to oil and lightning, against 5 upgraded Nagas and 120 Hoods. Moreover, he had no money to buy back, so he had to give up the remaining Nagas.
After such incredible luck, I decided to gather the Conservatories and go into the treasure zone. Took the maximum under my main despite 3 morale Griffins, then zone 3 next to the Castle. The treasure zone turned out to be rich in Dragon Fly Hives — got 38 pieces, and missed a couple more because Torosar appeared again in front of my main.
Fought with Tanth, the chain was slightly short of delivering meat, and Tanth had to catch up to it himself, but I had a serious advantage in army strength, and the opponent surrenders despite capturing the Castle.
Thanks for the game!
