OOC:
I'm not trying to railroad anything here, so I'm taking us back to the exit you found, but where you go from there is up to you.
The doors slam behind you, and the roar slows to a dull vibration under your feet, but it doesn't
stop. Whatever enchantment is on this room, it seems as if it doesn't stop time entirely. While she was asleep - or at least while she wasn't motivated to do anything, she was more or less silent, but now she's awake, and that roar could last quite some time.
The subtle shudder vibrates under your feet. If she wasn't slowed down as much as she is, there would be stones fracturing. As it is, it will be a while before there's any discernable effect, but you're sure there will be one eventually. You're going to need some help to settle her down before she becomes a problem.
You're also going to need to find those trogs. Fortunately, you're pretty sure you already found another way out. You head back to the room where you found the two kobold corpses, and carefully make your way down the dark hallway. It leads gradually upwards until it splits into two paths. One curves northward and carries the musty smell of stagnant rainwater. The other tunnel heads back down and the smell that wafts up from it is the unmistakable smell of troglodyte.
