Goshahri: The City in a Cave

From publisher blurb: Goshahri: The City in a Cave presents not a dungeon or even an adventure per se, although it includes a brief adventure. Instead, Goshahri is a place to be included as a recurring location in a Referee's campaign world. Adventurers may visit Goshahri, perhaps to seek black market goods, to curry favor from the Bandit King, to deliver ransom payments, to rest and recover from an adventure, et cetera. While visiting Goshahri, adventurers may find themselves embroiled in the mysteries and intrigues that simmer just beneath the surface of the Bandit King's domain.
