– As for the valkyries, they have inspiring stories. Both received the blessing of the Mother, although they chose to serve her in different ways. This is even evident in their stigmas, the attacking one versus the defensive one. And their character – eradicating heresy versus opposing those who do not love the Mother, gradually defeating them and convincing them of their own righteousness. Of course, there were conflicts on this basis… but that’s trivial. I think the Mother deliberately chooses people with different characters to serve her.
If there are books in the library besides the valkyrie ones, and Gulveig read them (she should have, after 20 years), then she also mentions them. And about the chronicle of the valkyries during the Artherian Schism, it’s not a book from the library, but she says in passing that she is also familiar with it, thanks to Calentia.
