On Top of Mt. Shasta: The Goblin Market

The Goblin Market - Getting lost's an easy thing in the Park, finding is often the hard part. Plenty of treasure hunters and mystics have wandered off the beaten path surrounding the mountain. Never to be seen again. Most become ensnared in the Goblin Market's wheeling and dealing. Squirreled away in the rough country, you can find vagrant tent cities intermingled with market stalls and vendors hawking a range of goods. Some human, some not. All are welcome to barter in the Goblin Markets. Just remember that money doesn't spend here. They're interested in baubles and ephemera, refusal gets the Gobbomeister Flim-Flam involved.
And nobody wants that.

Goal: They want more people to come to the park. Some to trade, some to lose.
Move: Constituents of the Goblin Market may take Sticky Bandit as an advancement.
Sticky Bandit - When you turn out your pockets looking for something, roll +Sharp. On a 10+ then you have what you need. On 7-9, you have something that's not quite close enough. On a miss, you had it but someone stole it from you.
Leader: Flim-Flam - At the intersection of snake oil and used cars salesmen, you'll find Flim-Flam. His loud suits and greasy hair camouflage his Otherworldliness, something he'd rather not discuss. The greedy goblin has grown fat and happy with the Underdim Compact and maintains it as best he can. If the Mole King wants a girl with green eyes, then that's what Ualichu gets.

Like this but WAY more flea market.
