Milady

Milady is a major character is Doctor Lautrec and the Forgotten Knights. She's proprietress of Le Repaire, a tavern operating underneath the Paris Opera house. She sells treasure maps to adventurers there. No one knows her true identity, how she acquires the maps, or what she'll gain by selling them.

Personality
Milady is as mysterious as the maps she sells to adventurers. She has a sharp tongue and is overly sarcastic. She likes to flirt with the Doctor when he comes to purchase maps, which often puts Sophie on edge. Milady frequently teases Sophie over her infatuation with Lautrec thinking he is too old for her. Often calling her "Madame" to get her point across. Despite this, however, she helps Sophie by selling maps with special Treasure Animatus that might help her confess her feelings.

Background
In Quest 14 - The Secret of the Mask, it is actually revealed that Milady's real name is actually Christine Leroux. An opera singer who is famous throughout Paris. At the end of the quest, Sophie actually sees the resemblance between Milady and the poster of Christine Leroux, but chooses not to say anything.

Trivia

 * It is likely that Milady's real name comes from the novel Le Fantôme de l'Opéra by Gaston Leroux. Her name comes from the character Christine Daaé who is also an opera singer. She shares her last name with the author.
