List of characters in the Camp Half-Blood series
May Castellan - Luke's mother who attempted to become the Oracle. Since Hades's power prevented her from taking it, she was driven crazy and instead received small glimpses of her son's terrible future. She made huge amounts of sandwiches, burnt cookies, and Kool-Aid for Luke, believing that someday he would return home. She also gave him a blessing to receive the curse of Achilles. It was shown that she had numerous clippings of Hermes from advertisements and many beanbag monsters sitting in the house and on the front lawn.
