We have the cast here, sounds like Annette is no longer Maria's sister since she now came from the Caribbean. Tera was another of the kidnapped maidens in Rondo alongside Maria and Annette (the fourth one from the game, Iris, is not mentioned here.) And Olrox, a boss from SOTN (and whose suit you can wear in Aria of Sorrow) is the vampire talking to Richter at the start. We also have Erzsebet Bthory, who was translated as Elizabeth Bartley in Castlevania Bloodlines. In Bloodlines she was manipulating global politics to start World War I, so I assume she's doing the same here for the French Revolution.

I wonder if they name Richter's mother, maybe that's their way of working Sonia into the story despite her game being non-canon
