Hey, look! Progress!
Now, here's where I take my hands off the wheel a moment and let the RPers start fleshing out the world, too. As long as it makes sense in the context of what we have so far, you guys are free to expand on any part of the environment. For now, that means the other parts of the cavern and places outside it. Because, well... These guys haven't really gone anywhere else yet.
Of course, you guys have limitations.
1. Obviously, don't go overboard and describe EVERYTHING.
2. Don't do stuff that'll give the chars a distinct advantage right away. They're climbing from the bottom, and ffs the place was just raided by humans. And we ALL know how greedy humans can be.
3. It has to MAKE SENSE.
We cool? We cool.
