The headless woman dresses in white and is known as Y Ladi Wen or Y Ddynes Mewn Gwyn. Apart from Calan Gaeaf she can also be seen at Hollantide. She exists to warn children about bad behaviour. If you should happen to meet her she may ask for help, or she may offer treasure or gold. She does not like greedy people however. Y Ladi’s Revenge is said to befall anyone who dies prior to disclosing hidden treasure, so be careful if she should meet you and offer you some of her gold that you do not take away too much. I don’t know why her head is missing, you will have to ask her yourself.
