As night falls, the forest around you seems to come alive with mystery. The canopy above is so thick that not even the moon’s glow penetrates the darkness that envelops your group. As you prepare your evening's encampment, the quiet of the night is pierced by the distant sound of conversations. The low murmur of voices is too faint to discern the words but clear enough to tell there are quite a few talking. You are still a ways from Fracha or where you expect to encounter the caravan of slaves, even if it swung north. Given you've heard them and they, presumably, haven't heard you, you have a moment to confer. Of course, talking might alert them to your presence.
Anyone wishing to talk out loud should make a Stealth check.
