well, derp and i are working on the historys, I have to see what he has said, but I did include that she was kidnapped by some magical experimentation facility for 'experiments'
good chance she was kidnapped becuase of such an ability, otherwise she might have gotten that ability due to it

it all depends on what the GM says

and with due to the bond, I meant she was born with it, but the bond activated it or something like that
the exact cause for the ability is still open for discussion depending on the GM's call
