Rena Stallone is Valerie's personal maid of common birth who has served Valerie for more than ten years since she was very young. She is described as having a rosy-cheeked expression and taking great pleasure in brushing Valerie's wavy black hair and applying rose oil to it. Rena claims that serving Valerie is the greatest honor of her life and believes people's worth is determined by their natural station in life. Despite this belief, she harbors deep resentment toward Lara for pushing aside the noble daughter of the Lord of Heidelbern. Rena is gullible and easily manipulated by Valerie, who exploits her misplaced pity and loose tongue. Rena knows a boy named Oliver who can hire a private investigator to dig up information about Lara's past. She was given a rose-shaped brooch adorned with a crimson ruby and teardrop-shaped diamonds by Valerie as payment for her investigative efforts.
