The party decides to continue on in the dark.  Fortunately Dawn's darkvision makes it easy to see despite the darkness, so he is still able to follow the trail without further trouble.  After following the trail for a while, continuing to follow the ravine, you eventually notice the glow of firelight coming from around a corner up ahead of you.

"Perhaps its time we put on the uniforms we found?" Pops whispers.

Dawn agrees with Pops and gets the uniform out of his backpack and charges into it.

Rather proud of his stitch-work Pops does the same 

Maythus grumbles as he puts his on, sure he looks silly.

What is the plan,  I don’t fit in a uniform.  Should I pretend to be a prisoner and we can surprise them?

Pops takes a uniform and tears off a strip bearing the bandit insignia. "Take this and wrap it around your arm and act like you are too strong to care about the dress code." Pops will use Minor Illusion to make Rockcrusher look like he is covered in wounds and blood.

Dawn will try to scout ahead to get numbers and report back. 

Stealth 12

Perception 7

Dawn sneaks forward to the corner in the ravine and peeks around to see where the light is coming from.  A short distance ahead, he sees the ravine widen out into a hollow in a plateau, in which he sees the raiders have made their camp.  A watch fire burns in the entrance to the camp just before the ravine widens out.  It's hard to make out a lot of detail past the light of the fire.

Dawn will go back to the party to report (do you want a 2nd stealth roll or is the 1st one good enough to get me back unseen?)

No sense standing around we either go in and find out or wait till it’s light.  We have come this far let’s go and introduce ourselves 

(No need for another roll)

I agree with Rockcrusher 

"Lets go" 

Rock will lead the group toward the camp

The party continues to follow the ravine to the camp, pretending to be another group of raiders that lagged behind the main group.  A raider by the fire at the entrance looks up as he hears the group approaching, but doesn't bother to stand or challenge you as you enter the camp.  As you pass the watch fire the ravine widens out and you enter the camp itself.  Enough cook fires are spread around the camp to allow you to see the basic layout, even in the dark, if not all the specific details, and provide dim light in most areas of the camp, at least near the tents, though it gets darker in between clusters of tents.

They've set up their camp in the hollow of a rocky plateau that’s shaped roughly like a horseshoe. The lower portion of the plateau rises gently from the surrounding land, but it quickly steepens and ascends to a height of about 150 feet above the landscape. Boulders form jumbled heaps at the bases of the cliffs. The level shelves and top of the plateau are covered in long grass, and brush and scrubby trees grow in patches, reaching 4-6 feet high.
