Call of the void (l'appel du vide) - The urge to jump off of or push someone off of a high place. It only lasts a second, and should never be heeded.
I thought a national park-ish area'd fit well, because they're full of high ledges and are widely known for people fallin' off 'em. The trees are a little lacking, but I didn't wanna risk shading/coloring them. I've tried to shade over tiny details and just ended up with columns of TV static. I think the shading on the people makes up for it, anyway.
