A small, primitive village has yet to discover fire, which is a good thing because there are highly flammable (but not otherwise dangerous) gasses in the air. The heroes, blissful in their ignorance, don't know that and think it a wonderful idea to show the locals open flame.
The local temple is known for putting words of wisdom of stele, in and anround the temple. These words of wisdom are normally temple proverbs or wise words, but sometimes they are "singing the praises" of any large contributor or a noble who grants them a special law. If you need proverbs and quotes for them, search a few quote and proverb sites, concentrating on religions like the temples. Put these quotes in a word doc or list, that way you can always "whip out" a bit of wisdom.
