She was also spotted at the table read. http://thewertzone.blogspot.com/2019/10/some-more-wheel-of-time-casting-news.html

I don't know any of her work but someone in another thread said she's black just in passing as saying she's been identified. My money is either Marin, I have no idea how old she is, or an Aybara. Perrin and Nyneave are the only ones who have no one in the series, I'm thinking Perrin as Nyneave at least is a little older and given that she seems to have been an only child and her father gets a passing mention.

Marin would be my guess. 

There's another woman at the table read who MUCH more closely resembles Egwene's actress (I think she's been identified as Lolita Chakrabarti?), so my bet is that this lady will be playing someone other than Marin.

Lolita works much better as Marin. 

 

Naana looks rather young to me. Maybe as young as early 30s or late 20s. Hard to believe she would be a teenager's parent, but that might just be me.

I'm going with Marin on this one as well, which makes me wonder who they're setting up to be Bran.
