They are

You wait for a moment, but don't hear any kind of commotion from past the gate. Taking this as a sign that no one heard you, you slowly push open the gate. Beyond the gate is a large cavern, probably the size of a castle's courtyard. The walls are lined with the same sticks and banners as the outside, and there are several small huts dotted around. You don't see any movement, so it seems like it's not only the guards that were asleep. There are also several goblins sleeping scattered on the cave floor. You had never really taken the time to look at goblins in your adventuring days, as it wasn't really necessary. They were about 3.5' tall, and weren't as skinny as you would have expected.

Your mind had perked up at the sight of the words class skill, but your hopes were quickly dashed. While you were sure there could be some use to it, it definitely seemed like it was just there to mess with you. Quickly putting your disappointment aside, you peek around the house to get an idea of where you are going. You're most of the way to the back of the cave, but from here you can see that the way out of here appears to be blocked by a hut much larger than the rest. As you realize this, you notice that a dim light has begun emanating from the hut you are right next to. Slightly panicked, you...
