Creation by an unrecognized genius.

By the way, I checked the saves from the two bird dwellings, and in principle, it can be explained. Although the luck is incredible and very suspicious, there is still a rational explanation: you need crystals and a bonfire for the air creatures, and you can take down a gargoyle along the way, plus there's a pile of gold behind them. And then, indeed, everything opens up one after another.
You can attribute this case to luck, a particular playstyle, or good intuition. I would like an explanation regarding another start as the Citadel, when the first hero ran along the dirt road, and there were blocks of Gogs along the way.
