Whoever she is, could she have been living in the Grimm-infested areas outside the kingdoms? She's wearing a Grimm-esque mask with what looks like feathers or fur hanging off it; I have a feeling it's not just a fashion accessory but actually the mask or head of a dead Grimm. She also happens to appear while the team is outside Vale (or, more accurately, on a speeding train heading towards Vale); possibly she became aware of them while they were in Mountain Glenn and has been tracking them for a while. It would certainly be a more realistic explanation as to why she appeared at that moment to save Yang, compared to some sort of mystical sixth sense (I'm assuming her Semblance is ripping holes in the fabric of space with her sword or some sort of spatial manipulation, and not detecting downed characters in need of dire deus ex machina).

If she is Yang's mother, that might explain why Yang could never find her mother, and it might also explain why her one lead was to a Grimm-infested area- because Yang's mother left the safety of the kingdoms to live in the wilderness for some reason. Or, at the very least, it might explain why such a powerful warrior could exist without us at least hearing about her before now.
