In the first week, I found artifacts for full ground control with relatively easy guards, and at the beginning of the second week, I collected them while having expert slowdown. I rushed into the main opponent's castle, thinking he was building a guild, but there was a Grail.
Thanks for the game!

After loading the save, I didn't enter the game and lost the Moon on day 121 due to my own mistake, along with the artifacts. I rebuilt on the first 1-2 days in the Fortress and had 4 Behemoths :D. I opened the obelisk near the castle and realized that I should have done it earlier.
After that, the only chance was to prevent control on the 2nd day at the opponent's.
On day 126, after 4 days of excavations, I activated the Grail, and I was immediately attacked. There were a couple of promising mages, but I needed a few more days to develop them. After the game ended, it became clear that even if I hadn't lost the Moon, the only chance was the Grail because against a 5th-level Archmage, Wings, and Colossus on the ground, with light guards, there was nothing I could do.
Thanks for the game!
