You casually just walk past the small kobold. As you get closer, she freezes in place, not moving an inch out of fear. Even once your past her she doesn't even move. For all you know she could still be frozen solid even after your some great predators snack.
Luckily, as you go deeper there don't seem to be anymore kobolds. However, you do find a diversion in the cave; two different directions, one's larger and ones smaller.
Its kind of obvious which way is to the dragon. But you ARE an adventurer, maybe you should do some adventuring into the unknown?
