The Charnel Pits of Reynaldo Lazendry

From publisher blurb: RL2 - The Charnel Pits of Reynaldo Lazendry is the second level of the dungeon of Reynaldo Lazendry. It's meant for the 1st advanced edition of the world's oldest fantasy role-playing game, but can be used with most classic editions with no problem. The second level details Reyaldo Lazendry's experiments in studying life and death...and undeath.
