This is a very far-fetched thought that popped into my mind. Her identity has been unclear from the very beginning, we don't even know her name yet and evidently in the maasverse that means something. I know it's crazy, but what if somehow she's a far more important and powerful entity? She held the cauldron and poured life from it, she's being seen as the creator of life. If she's the mother of the Archeron sisters then she gave birth to them and this all comes full circle when >!they're later Made from the cauldron!<. >!In SF, Nesta also feels a connection to her!<. In the maasverse, powerful characters are often known to hide their identity for greater purposes or personal motives. And that's exactly what The Mother must've done, concealing her true form and settling down in the human lands.

This theory is absolutely bonkers, I'm very likely way off and she might just be a witch or maybe a Fae. But I'm putting it out there.
