A line of light in the air, subtle but ever-present, a silent enticement to find out what it leads to.
You almost don't see it, it's so faint. You've been in this blasted wasteland, where nothing grows and the very air feels like it's sucking the life from your throat each time you breathe, for... days? Weeks, maybe. You did it, though. Slew that fell creature, the machine-soul grinding the life from this planet between its vast molars. You thought you'd die here, lost in this place, unable to see those you promised you'd save. But that was okay, you'd thought; as long as they were safe, that would have to be enough. You've tried to remember their faces, but each passing day has made them blurrier, as if even in death the titanic thing still clumsily tries to consume you. You... did do this for a reason. There were people to protect... right?
But now, this. The faintest of lines, only really visible from its very faint movements. But as your eyes adjust, you see it more clearly. A golden-green light, making you remember, truly, the sun passing through the aspen leaves on a warm summer's day. You can almost feel the cool breeze on your parched skin, wild strawberry taste in your mouth, and-
And her face. The one you did this for. Only for a moment, but it was there, she was real. You haven't always been trapped in this terrible place, with this terrible THING. Maybe... maybe there's still hope. Maybe there's a way out. A way home.
You take another lungful of dead air, prompting a coughing fit. Laboriously, slowly, you stand. You try to sight along the line - is that another glimmer, in the distance? Or is your mind playing tricks on you?
You'll find out.
