Taylor Hebert has been having an exceptionally bad day. Possibly even her very own 'worst day ever'.
Mind you, if asked, and indeed, even in the confines of her own mind, she will henceforth refer to it as her second worst day ever. It is a lie she tells herself, because humans are innately selfish beings, for whom personal suffering is much more sharply felt than second hand suffering.
It all began, you see, with a girl. Taylor's best friend in fact. She was never a very good girl - at least by the moral standards that Taylor Hebert lives by - but she was always at least content to apply her maliciousness to others, usually in largely small ways.
This girl, was called Emma Barnes. And for reasons quite beyond you (or Taylor, for she is the only source of knowledge you currently have access to) she decided, at the start of highschool, to become Taylor's mortal enemy.
Together with two other girls - whom Taylor, and therefore you, hate just as much as Emma - she has been systematically destroying any and all possible happiness, success, and stability in Taylor's life.
You know this, because Taylor Hebert has just triggered, while trapped in a tiny metal coffin full of almost literal poison. You know this, because you are the direct result of the Parahuman power that Taylor Hebert has just received.
In other words, using language that you are copying from your beleaguered Masters mind, you, are a projection.
To say that you are copying it from her mind however, is somewhat unfair. Or at least, a vast oversimplification of what is happening. Truthfully, it is easier to say that you 'received' it from her. Parahuman powers are, after all, not typically sentient. In that sense you are like... hm. Athena! A fully conscious existence that has sprung to life from within the mind of your Master. Everything you know, you know as a result of Taylor knowing it, which, at the very least, means you can skip the awkward infant years of normal human growth.
Which brings you to the now. Your Master has just used her power for the first time, with the simple command to free her from her confinement. This means that this is the first time you will ever manifest in a physical sense. You have, you feel, a vague sense of choice before you. One that - once you decide - will irrevocably change you to better suit your Master's needs.
