In between the second and third Cataclysm, I had met her.
Marie Rosalyn Scarlet, the first Vampire Queen.
A mother who searched for her immortal son, who was currently kept captive within the Vampire King's Castle. He has been used for over a century now, for extracting power and then supplying it to the humongous Vampire castle, despite not really being kept there.
Well, interestingly enough… the first time I realised that Lucia was using me was through her... It was the very first Vampire Queen, Marie Rosalyn, who told me that Lucia was planning to kill me, as she was dying right in front of my eyes. Things took strange turns and I ended up meeting her son in the most unexpected place from there onwards.
From what I remember, she told me about how she fought the Vampire King in her realm, only to be lost and then her powers taken by the King. However, she didn't allow the vampire King to use her power only until he told about the situation of her son.
