Ba and Laughing Crane,
After backtracking your way out of the Sunless Citadel and making camp up on the grass overlooking the chasm, you get a reasonably good amount of sleep. There's a light rain in the early morning. If you hunt for food, you're able to find some small game. If you search for some berries or plants to eat, they're not far.
If you wish to spend enough time to heal to full hit points here, that's perfectly fine. Nothing will come up out of the citadel after you at this point.
You do realize that the kobolds owe you a debt for rescuing the wyrmling. And of course, your job to find the brother and sister is still outstanding. But isn't it a lovely day out here, under the sun?
What do you do?
