Welcome to Jewel of the First Khan, an adventure in the Tales of the Infinite Planes series highlighting the different parts of the multiverse! In this scenario, the characters follow clues on an ancient map leading to a lost treasury of the first Great Khan of the Dao on the Plane of Earth, searching for the fabled magical jewel of the warrior-khan. But there’s more people interested in the gemstone than originally thought, and it soon becomes a race to be the one to possess the priceless relic against multiple foes! The adventure is designed for a party of 5th-level characters, but can easily be adjusted for higher- or lower-level parties.
A copy of Codex of the Infinite Planes is suggested to help add background to the plane and its inhabitants, but it is not required to run the adventure. In addition, one of the hooks for the adventure involves the World Serpent Inn, a sprawling tavern occupying its own plane of existence. More details can be found in Infinite Doors of the World Serpent, including using the World Serpent Inn as a group patron. Both of these products can be found on the DMsGuild.
