Quests from the Infinite Staircase

“The Lost City” is a dungeon delve with a dose of intrigue. While in the desert, the characters discover a ruined ziggurat peeking over the dunes. Inside the monument, they encounter three bickering factions of Cynidiceans who seek to reinstate their once-proud kingdom. Characters can align with one or more factions, reaping the rewards of membership at the risk of ostracizing rival groups.
As the characters explore the ziggurat, they slowly uncover clues of the tragedy that befell Cynidicea and its people. While braving clever traps, evil cultists, and restless Undead, the characters might learn that Zargon, the one-eyed creature that caused Cynidicea’s fall, still dwells beneath the monument. The party might even discover an entrance to the surviving Cynidiceans’ underground city (see the “Extending the Adventure” section at the end of this adventure).
The adventure concludes when the characters escape the ziggurat, either by returning to the desert or finding a door to the Infinite Staircase placed in a location of your choice.
