Sky. I just like the idea of flying too much to not go for it, really. XD

XD I hear ya! Okay, so maybe if you want the ability to be linked with theFamiliar (which it doesn't have too) then it could be something along the lines of sound, like she could be able to create a loud or distracting noise to disorientate or actually harm the enemy. Or something along those lines. 

Like I said, the ability doesn't have to be linked to the Familiar if you don't want to.
