Raiders of the Lost Tomb
Two thousand years ago, there were many tribes in Chult. The most influential of these was the Tabaxi, but nearly as powerful and as numerous was the Eshowe. Beginning 1,800 years ago, and lasting nearly 300 years, a bloody war between the Tabaxi and the Eshowe raged across the entire country.
In what proved to be the final large-scale battle of the conflict, the Eshowe released a monstrous and ancient evil from a valley deep in the jungle. This creature – a shadow giant that devoured honor and courage – attacked the great Tabaxi city of Mezro, nearly destroying it. The cost of this assault proved absolute for the Eshowe. Most of the tribe's warriors were annihilated by the shadow giant, who turned on them once repulsed from Mezro. The rest of the Eshowe were hunted down and slaughtered by Ras Nsi, a powerful and amoral protector of Mezro.
Legends of an enclave of Eshowe warriors, hidden somehow from Ras Nsi's murderous rampage, still circulate among the Tabaxi, and many fear the long-ago conquered tribe will rise up from the jungle one day to seek its revenge.
