The Church on the Hill

From publisher blurb:

The cleric regaled us with stories of the deeds performed by Sir Maron, then told us where he'd been buried after his death. We all thought it was worth a look - after all, great deeds are usually accompanied by great relics. The province where he was laid to rest is so odd, though. No one commits any crimes. No one gossips about their neighbours. Heck, no one really talks to anyone else. Every now and then, a villager will throw down their tools and leave the village, heading toward the Church on the Hill...

This is a system-agnostic dungeon designed to slot easily into whatever kind of campaign you might be running. Use it as a random settlement encounter or a local place of worship.
