## History

Arabella was the second child of the Cardinal De Mare by his mistress Lucrezia, and his final child overall. Even though she was born out of wedlock, her parents had a de facto marriage that was valid as a lawful one in the eyes of the kingdom, and Arabella was recognized as a legitimately born child of nobility. Growing up, Arabella developed a passion for music, mastering several instruments and even writing her own pieces. Sadly, her talents were overshadowed by the beauty and charm of her older half-sister, Isabella, who was favored by their parents as their ticket to elevating their family status by marrying her off to a high-ranking nobleman.

### First Timeline

Sometime after Ariadne was summoned to her father’s home to take Isabella’s place in her arranged marriage to Count De Como, a plague came to the capital of San Carlo. Arabella contracted the disease and died young as a result.

### Second Timeline

When Ariadne is reborn in the past, she and Arabella get to a rocky start. Arabella blatantly insults her for her illegitimate birth, to which Ariadne subtly responds with an observation of how her parents prefer Isabella. In a blind rage, Arabella lungs at her, only for Ariadne to dodge, causing Arabella to accidentally push Isabella instead. When their father appears and demands an explanation, Arabella lies abd says that Ariadne was the one who pushed Isabella. Ariadne claims that Arabella was playing too roughly and accidentally pushed Isabella, which Arabella denies. Ariadne then tells her father to ask Isabella for the truth, to which Isabella takes Ariadne’s side and confirms her story over Arabella’s. Arabella is horrified by her sister’s betrayal, and subsequently punished by their father for hurting her sister and lying about it.

On the day pf the state mass, Arabella is in a Gallican language lesson with Isabella when Ariadne walks in, stunning Arabella with her fluent Gallican. Arabella accuses her of cheating, but Ariadne remains kind towards her. Later that day, Arabella attends the state mass with her parents and sisters, where she, among many others, witnesses Ariadne publicly denounce the Apostle.

Sometime after this, Arabella comes into Ariadne’s new bedroom, claiming to be watching her, but Ariadne senses the child is simply bored, noting that Arabella does not get much attention from her parents compared to her older siblings due to her lack of value. Ariadne humors her about her lute that she brought in, to which Arabella proclaims that she is a prodigy, and plays an original piece, impressing Ariadne and Sancha. Ariadne asks if she could get her mother to buy her any different instruments, and Arabella notes that she wishes for a pipe organ to play it at a church service, but Lucrezia has refused her request. Ariadne suggests that she ask Isabella to ask for the pipe organ, saying that they would oblige any whim of hers in a moment, which Arabelle bitterly and secretly agrees with.

Arabella asks Isabella to ask their mother for the pipe organ, but Isabella initially refuses, saying it would be frivolous, despite Ariadne internally noting that Isabella’s own foriegn cosmetics and jewels are probably much more frivolous. She notes that she was impressed with Arabella’s hymn and gets her to play it for Isabella, who is indeed impressed as well. Taking Arabella aside, she agrees to ask Lucrezia for the pipe organ, in return for Arabella letting her take the credit for the hymn writing and present it to noble society. Arabella agrees, albeit dejectedly.

Upon the debut of the new hymn of the church, Isabella takes center stage as the piece’s claimed creator, but upon the big moment, she fonds herself unable to read the sheet music Arabella wrote for her. Arabella, panicked and without thinking, runs up onstage and corrects Isabella, inadvertently outing herself as the true composer and humiliating Isabella in front of noble society, especially Count Cesare De Como, who publicly mocks her before everyone. Later, at home, Arabella is blamed for her sister’s embarrassment by her and their mother, the latter of whom strikes Arabella when she protests their accusations. Ariadne finds Arabella in a despondent and takes pity on her, hugging her and offering her comfort.

After this, Arabella grows closer to her illegitimately born sister, and vice versa. Ariande decides to save Arabella from dying like in the first timeline by sending her away to a special school aboard, so that she is far away from the plague when it comes to the kingdom.

While Ariadne is away to secure Arabella’s acceptance into the academy, Arabella gets an idea to surprise her with a gift when she returns home, as a token of thanks . She sneaks into Isabella’s bedroom and finds a clasp, which unbeknownst to her was used by Isabella to tamper with Ariadne’s brassiere during her debut ball. Isabella walks in on her and sees her with the clasp. Not wanting Arabella to inadvertently show evidence of her trick, Isabella chases her to try and get it back. At the top of the stairs, Isabella reels back her hand to slap Arabella, who, as a result, trips backwards and falls down the stairs, knocking her unconscious. Not wanting to be blamed and sent to a convent, Isabella leaves her sister for someone else to find .

The servants eventually find Arabella bleeding on the ground and carried her to her room. When she awakes, Arabella hears her mother blaming her for falling for defying Isabella, taking her older sister’s side, breaking the heart of her youngest child. Devastated, Arabella succumbs to her injuries and dies before Ariadne’s return home to give her the acceptance letter into the academy .

After her death, Ippolito heard rumors that Arabella had not really been the biological daughter of the Cardinal, and confronted his mother with such accusations, which she vehemently denied. But, as Ippolito cruelly discovered later on, the rumors were half-true, only it was Ippolito himself, not Arabella, who was the child of another father.
