I'm starting to detect a trend with Tchaikovsky's stories. They are almos always about The End of the World, or The End of the World as We Know It. And he is good portraying this.
"The Hyena and the Hawk", or rather the whole trilogy, it's not the exception, but he was announcing this from the beginning of the story in book one "The Tiger and the Wolf". You could say "this is the one about the gods and the souls, and what we destroy just because we are not capable of notice that it exists".
I quite liked the ending of this story.
