Trivia

 * The history between Castaspella and Shadow Weaver was part of their back story in the original She-Ra: Princess of Power series. However, the name 'Light Spinner' was only used in the UK Masters of the Universe and Princess of Power comic magazines. The Masters of the Universe Classics line which began in 2008 elaborated on Shadow Weaver's origin by by revealing her true name to be Beatrix, with Light Spinner being a pseudonym she used while studying under the wizard Norwyn with Castaspella.
