I mean, having to move up a step and be replaced as Queen by the Lady is exactly what would happen if Mab did pull off a coup on Mother Winter...

I'd call it inconclusive from the given info. Kringle and Vadderung are "technically" separate characters too, and I'd almost be surprised if both the Mothers don't have a range of different hats they can put on.

Very much this. Also baba yaga is supposed to have iron teeth. Very few thing in any more have much to do with iron and she's one of them. Of course you also have red caps in Fey lore with their iron shod boots but that doesn't seem to be a thing from what we saw of daddy red cap. Then again he might be a red cap not the red cap.



As for The Nox thing it also fits with darkness connection she is literally the first night that then gave birth to the day.

Been gone for a while but has anyone made the obvious connection to Baba Yaga?

Also Nox seems like a fitting one also. The first night who birth death destruction sleep dreams and pretty much everything that makes the world work. A primal goddess (if thats even what she was) older than the titans who's father was the raw chaos from which everything was formed. Even Zeus wouldn't mess with her

Honestly I think that it is earth. Way in the future.  Albion is the english spire. Olympian greek. And so forth.
