From the publishers blurb:
Deep in a dark and twisted swamp lies an ancient temple. Once a sanctuary to a relic most holy, now a rotting ruin of ancient lore and treasures, guarded by monstrous beasts...
Players arrive looking for the fabled religious artifact, only to face a horrible blood curse in its many physical forms. They soon discover a group of Voiceless dead here as well, racing to find the artifact first!
Temple of Old Faith is an exploratory dungeon crawl for a third level party using fifth edition rules, although it's easy to adapt to any game system. Featuring:
An original monster design, partially generated through a randomized table.
Clear and straightforward layout for each of the three levels, with keyed maps.
Multiple approaches and paths available to players, combined with rich random tables for a different experience every time.
Open-ended resolution, completely dependent on players' actions.
