Head of State
The party sets camp for the night and while foraging for food encounters an abandoned sanctuary with pillars and hanging garden structures. Scattered about are exquisite statues in various poses. Oddly the statues are from all classes. Peasant to Noble and Adventure alike. The players have walked into the lair of a Medusa.
If the players survive they will note one of the statues if that of a near by mayor or high-ranking official from a rather large and wealthy city. Returning them could prove worth a hefty reward. Or maybe even a boon for being the Mayors savior.
If you wish to expand on this you could have the party be harassed by bandits that think the statue(s) must be very valuable and wish them for their own.
