You aren't sure what the doctors did beyond binding her ankle in some tangled vine, but it seems to have taken the pressure off and she can walk reasonably well. Where she has trouble is with pushing herself up through a hole in the ceiling that leads to the roof. You give her a boost and then pull yourself up as well.
Being near the center of the city, you have about as good of a view as one can hope in such a dim light. You see the girl scanning and counting. From what you can tell, most of the lizards are pouring in from a gate opposite the one you entered. Several guards are trying to force the gate closed, but then a blast echoes through the vast chamber, knocking the gates off their hinges. You look down and realize that the girl is holding on to you and looking very afraid.
As you touch her hand, she snaps out of it and the face is replace with stern concentration. She walks over to one edge of the roof and starts fumbling with loose straps of vine near a line that runs over head. As she does this, you hear even more yelling from the destroyed gates. As you look over, you see the largest lizard you have ever laid your eyes on.
It's easily larger than a horse, and you wonder if it might be a dinosaur, though it still moves like an alligator or crocodile. Several men try to attack it with their spears, but it is fast with its jaws and flanked by smaller lizards. After a few moments, it seems to notice you staring at it, as it looks up at you.
You take a step back and look over at the girl in time to see her toss a loose vine over the taught line above and zip line away. There are more loose vines that you can use to follow her, but the direction of the cable was not back to the gate you came in by. You think you can find the way and look back at the hole you came in from.
