One of the daily themes in Valley of Blue Snails will be that of superstition. This is mainly due to the prevalence of spirits. Most of the folklore is simply true, and the unwary and unwise can find themselves dragged into a stagnant pool of water by a horse-headed water spirit if they do not take heed. Needless to say these superstitions are taken rather seriously by most intelligent races. Even your run of the mill Kolbold will make an offering of regurgitated fish on a lillypad before crossing a flowing river.
So since superstitions will be an every-day role-playing opportunity I should denote what exactly they are. This will obviously be a growing list and it is certainly malleable towards which ever races or culture are played. No two races would do things the same. Even nearby towns will delineate somewhat on the exact practice of these superstitions, so they are by no means written in stone. The main thing is the effort is made – the spirits will definitely take notice if they are intentionally ignored, and will repute spitefully.
