Sometime prior to 1637, Louis XIII became King of France and married Queen Anne of Austria. On the night the couple was to consummate their marriage, their chateau was attacked by assassins armed with future technology. Fortunately, the Legends had detected the time aberration and had disguised themselves as members of the Royal Guard. They used their powers and their own future technology to defeat the assassins and protect both Louis XIII and his wife, ensuring that the couple would consummate their marriage and the timeline would remain unchanged.
Queen Anne of Austria mentioned to Sara Lance that Louis XIII "...often enjoy[ed] the company of his male courtiers," implying both that he was not heterosexual and that the couple participated in a sexually open relationship.
