Return of the Lizard King

Publisher's blurb: In Chult’s Valley of Dread, warring tribes of lizardfolk have kept each other in check for centuries. As the tribes slowly fall under the sway of a new leader, omens point to the return of an ancient threat: the demon-spawned Lizard King. Adventurers from a far-away realm find themselves in the middle of the fray. Their heroics could save the land from terrible evil, or it might play a part in bringing about doom! Return of the Lizard King is an adventure for characters level 1-4, playable as a lead-in to Tomb of Annihilation.
