If there is one thing that works faster than trade in Katapesh it is spreading of rumors about money to be made.
The next day during another walk through the city while browsing the display of a jeweler's shop a woman comes standing next to the group, looking at the wares on display on the table too. Without looking up she starts talking. "Far away from Kelmarane you are. How do you like the big city so far?"
She picks up a necklace that seems to have caught her interest. "I've heard you brought something along with you. An artifact. Such a thing can easily become a heavy burden. I could help you with that. I'll put 30,000 gold in your pockets and you wouldn't have to worry about that anymore."
