Hermione knew from a young age that she hated heights. They unnerved her. She would never forget the day that she had accompanied Charlie Stark to the Iron Islands and stood atop one of the cliffs. She would never forget watching the waves crash into the side of the cliff, never forget slipping in the mud and falling far enough down that, if she hadn't grabbed onto a handhold and hoisted herself back up, she would have died had her body hit the water.
