During this birthday luck period, one's fortune will be unusual, either good or bad in tiny, quirky, often unnoticeable ways. It is customary for people who are content with their lives to stay indoors during their birthdays in hope of avoiding situations where a freak of chance may intervene in their fate. Except for birthdays, this luck period is a minor matter for the average person. For anyone who wishes to be a magician, it is crucial.During the birthday luck period, it is possible to perform magic. It is not, however, easy. The study of magic requires years of practice, which cannot be achieved to any significant degree during the few hours each year of an individual's birthday luck. The solution is to transfer the essence of one's magic (one's "luck") from one's physical self into another thing or being. Then, so long as one is within three paces of the vessel containing one's luck, one can practice magic throughout the year. This transference, called investiture, can only be done during the birthday luck period.Investiture is extremely difficult for novices.
