Thanks guys!
So here is what she has decided upon. (Keep in mind we are Gloranthan noobs, and advice/suggestions are more than welcome!)
She was a dragonewt who really failed during her last lifetime. Was really evil or something. Instead of reincarnating in another dragonewt form, she reincarnated as human.
Now, this part we haven't totally figured out yet, but she wants to be a necromancer and to have her old body as an automaton/mount. (It wouldn't be any more powerful than a bison or something)
What she was thinking is that she was really advanced, almost dragon, and then really messed up, OR alternatively she was cursed by a rival/god/etc.
Thoughts?
