Climb through the vents

Taking a deep sigh, Yang decided she would climb through the vents. It wasn't the most ideal or glamorous solution, but it was better than sitting in the dark for hours on end.

Yang walked over to the lockers directly beneath the vent and scrambled on top of them, loosing her footing a couple of times but eventually being at eye-level with her target. Being so close to it, Yang could see the vent itself was maybe two feet on a side. It was definitely possible to crawl through it, it'd just be really uncomfortable.

Looking closely, Yang saw that the bottom two screws were missing completely. Wrapping her fingers around the grate, she had pulled it about halfway up when the top two screws snapped in half. Yang jumped in surprise and nearly fell off the lockers before she realized what had happened. Not sure what else to do with the grate, she just dropped it to the floor where it hit with a loud clang. Yang winced at the sound, but quickly turned her attention back to the opening in front of her. As far as her makeshift flashlight could show here, there wasn't anything blocking her path forward.

"Here goes nothing," Yang muttered to herself as she climbed into the vent, getting on her hands and knees and beginning her trek forward. She could feel the cold metal of the vent brushing against her bare back as she moved along, sending a chill throughout her entire body.

As some small measure of good luck, the metal walls of the vent allowed the light from Yang's aura to reflect off of them, sending them a little further ahead of her. In the end, it only gave her a few extra feet of sight, but Yang was going to take any victory she could get in a situation like this.

It was difficult for Yang to tell how much time had passed, or even what progress she was making. One duct looked just like another. For all she knew, she was going in circles.

After some time, though, Yang came to a vent much like the one she had climbed into. Feeling herself get excited, Yang hurriedly crawled forward and pressed an open hand against the grate. To her dismay, this one was fully secured at all four corners. Not feeling deterred, Yang contorted herself so her feet were towards the grate and laid on her back. After taking a few moments to psych herself up, Yang kicked both of her legs out against the barrier. To her relief, it gave way almost immediately and fell to the ground below. Yang quickly pushed herself forward, dropping out of the vent and looking around to see where she had found herself.
