However, the issue of realism is not so clear-cut - on the one hand, I want to consider all this from the point of view of physics and realism, but on the other hand, this is a magical universe where any absurdity can be explained by a magical background, so I'm not sure.

Расщелина по склону ниспадала.
О, никогда под бледною луной
Так пышен не был тот уют лесной...
