Caster is Doņa Maria Blanca de los Cristales, the ephemeral princess of the
Reino de los Cristales
Kingdom of the Crystals
who appears in the Filipino epic
Ibong Adarna. She fell deeply in love with the dashing Don Juan, who had come to the kingdom, seeking her. Much like the story of Jason and Medea, she helped him overcome her father’s trials and win her hand.
Maria eloped with her lover, and was soon left near the prince’s kingdom. Maria hoped that Juan would come back to her, but when she found out that he had forgotten all about her by reuniting with his first love, she fumed with rage and, using her magic, first tried to cajole her wayward lover into remembering her. When that failed, she threatened to use the power of her magical flask to drown the entire kingdom unless her wish was granted. Fortunately for everyone present, Don Juan remembered his feelings for her, and they were married and lived out their days in the kingdom of Maria’s father.
....Or so the story goes. In truth, Maria and Juan’s marriage was simply one of convenience, for Maria had only wanted with all her heart to see the world outside the kingdom, and Juan wanted the fairest, most beautiful bride in all the land, and so their union was destined to be cold and loveless. While she eventually grew to love him, he did not, for the memory of his first love had left a scar in his heart that was too difficult to heal. Maria Blanca was trapped again, in a marriage that granted her only despair and a kingdom that would have been hers alone.
Summoned into the modern era, Maria Blanca’s personality is something that could be described as lonely, though it could easily be mistaken as standoffish given her royal upbringing. She complies with most of her Master’s orders (so long as they are within reason), and very rarely speaks her mind, which probably paints her as an ideal housewife.
She likes the sea very much, and will visit it as much as time and location will permit. She dislikes dogs and canines in general, but this has no real basis, save for the fact that her husband’s first love had one, and she is loath to remember her. She has a rather simple wish for the Grail, which she does not divulge very often due to its meager and selfish nature. She wishes to have the tip of her left ring finger restored to her, as she had lost it due to a carelessness while undergoing hardships for Don Juan’s sake. It seems she wants to forget enduring pain for someone who does not see her the way she sees them.
