Lorin's Chasm

From the Introduction Lorin's Chasm is a short adventure for four 5th-level characters that takes place in the caves beneath a remote monastery devoted to the sun god, Pelor. The monastery sits atop a mountain range and has a large complex of caves beneath, most of which are used as tombs for the priests who have died there over the centuries. The monastery and the adventure can be placed easily on almost any D&D world.
