[ It's the first time there's been any sort of recognition of a term from her world, and though what Clarke goes on to describe sounds at odds with her idea of aura, it still makes her perk up a bit. There's also a slight tilt of her head as the list of types of people here (Vampires? Fictional in her world, but sure, why not. Augmented humans, what counts as augmented? Gods, what? Robots, well, one of her best friends is a robot, but she's also the only robot with a soul in her world, so...) goes on, wow this place is... a lot. ]

In my world, our aura is a representation of our soul, but... not quite like that? They're colourful, but only one colour; mine is red, my sister's is yellow, some of my friends' are light blue, purple, green...

[ She gestures vaguely, the list goes on and on. ]

Everyone has one, but not everyone unlocks the more... practical, aspects of it. [ what's the simplest way to explain this... ] When you unlock it, it's sort of a personal shield. You have to break it to actually cause physical damage to someone.

And it means you can unlock your Semblance, but that's a whoooole other thing.
