I was attracted to my witch tradition in part because it works with the fey (or fairies, or what you will). Contrary to some lore, we find that they like being called with bells. Our fey caller is hung with goat bells.
The fey for us include all spirits that aren’t deities, but I particularly think of nature spirits—the people of the place, whether connected to particular animals, plants, or locations, or to the greater spirit of place. I think also of weather fey.
