The Lost Crown of Tesh-Naga

From the Introduction:

This adventure is a simple delve that puts a new twist to the standard. The players will play monstrous characters, each with a central goal, but with conflicting agendas. The characters all
want to work together to get past the dangers of the dungeon and recover a lost artifact. However, each character wants to claim the artifact as theirs. As monstrous characters, expect and encourage PC‐on‐PC conflict throughout the adventure, and a bloodbath at the very end. The adventure site is littered with
dangerous terrain intended to provide tactical advantages to creative thinkers.
