Her knees throbbed from the hard stone and it felt like she’d been crawling for ages, but she continued moving forward. Caroline didn’t think she could turn around even if she wanted to, and she stopped every so often to stretch each leg out and take some of the pressure off her aching knees. The orb stopped, hovering in the space ahead of her, and Caroline quickly caught up to see why. She found herself faced with three possible directions to take. She groaned, not wanting to make the wrong choice and find herself crawling through the hidden spaces of the academy for hours on end. She could continue straight ahead, where it looked like the tunnel leveled out. Or, she could go left, which saw the tunnel continue to slope or go to her right, which sloped upwards. She ruled out the right side, not wanting to head back the way she came, but was uncertain which way to go from there.
