How much control do we really have over our lives?

It's a huge question, one that countless philosophers have spent endless years pondering. Certainly not something that a simple science fiction tale can answer. Nevertheless, it's always fun to touch upon these big questions just enough so that they tickle at the brains of readers.

Kiellen chooses to wear the suit. No one forced her to join the Mechalarum ranks - she did it of her own accord. But did she really have a choice? From an early age, there was nothing she wanted to do more than take to the skies. An internal force nagged at her, relenting only once she'd "chosen" to become a pilot.

So, being in the suit is (possibly) "her choice." Once she's in there, though, the suit tries to force her to act a certain way. She "chooses" to fight back, because her indomitable will will have it no other way... But she's in control of her will, right? Ultimately?

Choice is complicated. I don't have any answers. I just like to inspire questions.
