Nobody ever guesses my author-insertion characters without being told. *g*
But the two who are most like me are Elspeth Dunsany (come on, she's such an intentional Mary Sue! She's even named Elizabeth--and she had sparkly eyes! and everybody falls in love with her! And she's the world's smartest Canadian!) and Matthew Szczegielniak.
Matthew is really just me with a penis, a better build, and more magic powers. And different angst.
