Relating to the discrepancies between ABP, PPM, and ATG: 

In ABP, Mabyn lives a long life and dies of old age. Most importantly, she comes from Real Earth. What I'd like to do is rewrite her story to follow this one, in how she IS from Middle Earth, but has convinced herself she isn't because she'd rather believe in her fantasy than her real history. Again, I'd like your input on that; see my most recent author's note at the end of ABP. 

In PPM, Mabyn dies of illness and injury, as she's expected to. That's honestly how I thought the real story went, until talking more in-depth to you-all about how her story could go as an original fiction. So I might rewrite PPM in the future to include her. Probably, actually. 

This is the basis of all you need to know about confusing Mabyn details for this story. Carry on.
