Dark is deathly afraid of heights, after falling almost to her death, causing her to get anxiety from it. The highest she will ever be will be about 4ft in the air, even then she's still kinda hesitant. If she's in a building, that's fine, as long as she's not near any windows or ledges were she can look down and have an anxiety attack. If anyone jokingly pushes her or anything, she will snap and choke the person until they apologize.
