About 100 years ago in the nearby town of Skrzyńsko a strange occurrence took place. All priests that served in the church mysteriously died within a very short time period. Panic spread as the inhabitants feared that they where cursed or that the devil invaded there church.
But after a few months investigators found the source of the unknown deaths; a giant half kilo spider. This spider had a nest on the attic right above the priests dining table. Here he sat while drops of poison dripped into the food of the priests. This poison's strength and current medicine meant certain death to all whom ate it.
The spider was on display in the town hall but has been lost since WWII.
