Unexpected Discovery

From: Carlos Light
Description: I wanted to catch up with whoever was walking in the fog, because it could only be a Scavenger. But the fireflies flew away, and the fog thickened... How could I return? And why has someone put a combination lock on my haversack? I don't remember the combination, of course. Bring me some tools, and let's see what's in the haversack.
Completed: We've unlocked my haversack. There's my lamplighter's set... and my jar of fireflies! But it's tied with a silk scarf, which in definitely not mine. I now remember going back through the fog. I was led by a woman. A perfume aroma emanated from her, as well as this scarf.
