I agree completely, from an outside point of view. For example, there was a shoutout in the very sentence Baba Yaga was introduced.

Past Professors of Defence have included not just the legendary wandering hero Harold Shea but also the quote undying unquote Baba Yaga, yes, I see some of you are still shuddering at the sound of her name even though she's been dead for six hundred years.

I claim Baba Yaga is important and Harold Shea is a decoy. Yes, I also think my hypothesis sounds arbitrary and a bit crazy.
