They're a fantastic organization to hire out freelancers, because they need a literal pair of hands (or 4) to lift up a priceless painting from one subterranean hidey-hole and carry it safely to theirs.
(Also here's a link to the player's handbook for Esoteric Enterprises, with which one can create ghosts.)
From Wikipedia
WHAT DOES THIS GHOST GANG WANT ANYWAY
- Enchanted fresh food to actually eat.
- Ancient vinyl pressing of ritual music.
- Large (4' x 6') oil painting, frame optional.
- Unenchanted stone idol.
- Large pile of enemy's wealth to be destroyed dramatically.
- DVDs and DVD player. Holy oil to anoint such that they can push the buttons.
- Hookah, brick of undergrown-cultivated herb.
- Blessed salt to keep out uninvited spirits.
- Silver-coated sword that they can wield.
- Rune-carved zippo lighter shipment. They don't run out of fuel.
- Ectoplasm-filled jar, the remains of one of their own.
- Liber Noctis, a book of binding ghosts. A furnace to destroy it in.
- Soul trapper's scalp or forefinger.
WHO HAS IT WHO IS TERRIBLE
- A thief-lich (HD6) and her disciples.
- Null soul zone-dwelling scavengers.
- Overly large cryptid.
- Nearby police precinct.
- Bank vault, front for some undead businessfolk.
- Devotee of the Void and their flock.
- Rival ghost gang.
- Urban explorers, last seen diving the depths.
WHERE DO THEY HOLE UP
- Underground, an abandoned subway stop
- Aboveground, in an unknown safehouse
- Underground, beneath a small settlement of worshippers / traders
- Underground, in an automatic sewer processing system
- Underground, in an ancient building that was built over hundreds (?) of years ago but looks like it's from the 1980s
- Aboveground, a squat atop an abandoned (?) building
Oh yeah, obviously if you get a location or WHO HAS IT from the What they want table, don't bother rolling on the later tables unless you want.
