The world narrows down to a single point--the girl she's crawling towards--and then--
She doesn't vanish, exactly, but there's something else there instead.
Instead of walls of forbidding stone she is surrounded by a dome of glowing crystal, perfectly visible in every facet even though it's as far away as the sky.
A six-pointed star appears in front of her; or perhaps a snowflake. Each point is tipped with two glowing spheres. She shouldn't be able to, but she can tell what they are. Mostly. The spheres that represent the two benefits she hasn't figured out and the downside she hasn't figured out are opaque to her. A power. A price, some kind of non-voice whispers from nowhere. A power unsolicited, a price forcibly paid.
You did not choose this. But it is yours, nonetheless, and you will do what you need to protect it.
The crystal sphere fades away. It is replaced by a series of images--of Edie, mostly, fighting and falling and bleeding and getting back up all the more determined.
You cannot save her from herself. But you can stand by her side.
A shield, catching a blow that would have felled her. A hand on her shoulder, reminding her what is at stake if she fails, if she is reckless.
And there is so much more to you than the price of power.
She is the kind of person who would move a world, given a lever and a place to stand. She will have to find the latter on her own, but the former is offered to her.
Will you take it?
