Reflections Beneath the Sand

From publisher blurb:

5th Edition Mini-Dungeon for four to five characters of levels 8-9

The port city of Tarakesh lies on the southern edge of the Great Desert. It is a harsh city filled with pirates and tomb raiders in search of ancient crypts to plunder. In a seedy tavern the party meets a beautiful pirate captain named Nicole Christine. She is selling a map which leads through the desert to a tomb filled with riches beyond imagination. She would investigate herself, but alas, her crew grows restless spending too much time ashore.

For the mere price of 250 gp, the party can have the map, and all the riches the tomb contains!
