Oh yeah, for sure. The Brothers Grimm and Hans Christian Andersen even make a few appearances in later chapters of World Stars.
I’ve always thought that the idea of Russia’s heart being frozen has really similar parallels with what happened in Andersen’s “The Snow Queen.”
Basically, shards from a magical mirror get splintered in a little boy’s heart. He slowly begins to freeze and looses his sense of humanity, becoming increasingly aggressive and cruel without realizing it. There’s also the antagonist of the Snow Queen, a rough female equivalent of General Winter.
I guess I’ll have to make a post on that some time soon, huh?
