The Village Hall's witch

Today, we went to a nearby village for a special messy play day for babies, toddlers and children. It was in the village hall building. As an ensign, the hall has a witch, flying on her broomstick right before a crescent of moon. I have no idea whatsoever why they have a witch as a village ensign, but I want to find out and will work very hard to solve this mystery. I think there is at least one good scary story to write for Halloween, inspired by this witch. Also, as a bonus anecdote, I showed it to Wolfie, who was very impressed. And he now knows how to say witch and sorcière...
