From publisher blurb:
Tomb of the Viper Prince is a Fifth Edition adventure intended for three to five characters of 6th to 8th level and is optimized for four characters with an average party level (APL) of 7. Characters who complete this adventure should earn enough experience to reach one-third of the way to 8th level. The desert tomb of an ancient and powerful prince has been uncovered, and a powerful artifact lies hidden within. This adventure takes place in the Freelands campaign setting but fits into any existing campaign with a desert in which a hidden tomb can be placed with only a few modifications.
This one-shot adventure is designed to easily be dropped into any existing campaign with just a few location name changes!
