Gosh, sorry for that late answer! I haven't been here for ages.
It's more like a concept I have. I'm not really good at storytelling, so I wrote a paragraph about her in my Russian blog. In brief: her monster child was stolen by the king of the firm land and she gone mad and started wrecking ships of that kindom in hopes to find her child. At the time the kingdom was tottering to its fall because of merchant loss and decision to bring back the Devil's child finally dawned upon the king. But it was too late, she completely lost it and she didn't recognize her child. What a sad demise.
Oh my, sorry for my English, in Russian it sounds much better
