Many want to confuse Mennie with Bast and some even call her that, but she is, in fact, Ma’at. Bast was defeated by Artemis when the Greeks invaded Egypt. That war is also what cost Sasha his entire family. Before Bast died, she passed many of her powers to Ma’at in order to keep Artemis from gaining them. It’s because of that dual duty Ma’at was forced into that people now confuse them.
