The Kremlin (a Castle in the style of the Ancient Slavs)
Here it is – the Slavic soul, and such a soul has no place in Ashan. One could only adapt Eastern independent cities to resemble the Kremlin. That would be cool.

The ancient Slavs had neither castles nor, moreover, kremlins. And the Kremlin in its natural form (as well as the Slavic soul) does not fit into the concept of Ashan in any way. And what about house spirits, kikimoras, leshies, and zmei-gorynyches as creatures?
