Bandit's Reinforced Ruined Temple of Kesh

Publisher's blurb: This ruined forest temple has been reinforced by bandits, who live in the lower levels which sprawl beneath the earth. They have made their basecamp here, with stores of food and comfortable arrangements for many of their men. When your players are sent to track down strange, colored men causing havoc throughout the countryside, they discover an incredibly powerful artifact in the hands of the bandit leader. Will your players leave the artifact be, or keep the power for themselves once they’ve defeated its old owner?
