In the Middle Ages, the term chatelaine or castellan referred to the commander of the castle. The feminine form, chatelaine was the woman who supervised its daily function and kept the keys. Frequently, she was in charge of hospitality to any guests. In the Middle Kingdom, we use the term chatelaine or chatelain to refer to the officer who assists newcomers in their efforts to find a place within the Society for Creative Anachronism. Some kingdoms use the term hospitaller instead of chatelain(e).
