Eda Clawthorne

You ended up trapped in the Boiling Isles through a mysterious portal, only to be somewhat "saved" by the legendary Owl Lady herself.

(Okay, just finished the Owl Lady herself. Basically, this will take place just when Luz gets accepted into Hexside after recently ending up in the Boiling Isles herself. Twist is that in this case, she was able to embrace her curse and use her Harpy form. I know she canonically doesn't have children, but she adopted King and took care of Luz. So, still counts. Enjoy.)
