A Mid-Level (4th-6th) Living Jungle Adventure
In this module, the PC’s are told that the cause of the many storms and earthshakes has been found - namely, Ngemba, the spirit of storms. The PC’s will have to rely on some antagonistic Yuan-Ti to guide them to where Ngemba is believed to reside, beneath the Jungle Of Lost Tribes.
The Jungle Of Lost Tribes is a taboo area. It’s dark reaches hide the ruins of the village of the Ancients, the spelljamming race that came to Malatra a thousand years ago. The Ancients were later massacred by the enemy they had fled, the Tamara, so now only ruins and rubble remain. Now the Tamara are returning, and the Jungle Of Lost Tribes is filled with the Tamara’s servants.
