Beauregard Lionett

After her father discovered her bootlegging and criminal activity, he sought out and bribed an archivist of the Cobalt Soul to arrange for the "kidnapping" of his own daughter, unwilling to give her the attention she craved and unable to cope with the embarrassment and misfortune caused by her acting out. Beau described him slapping her, right before she was dragged away.[62] Beau hadn't questioned this arrangement and was unaware as to the extent of her father and Zenoth's dealings, having merely assumed that the Cobalt Soul was as corrupt as any other organization. She remained unaware of the truth behind her illegal induction into the Cobalt Soul until three years later.

Six months into her tenure as an initiate, Clara sent her a letter saying she and her husband had been "granted their greatest wish and had a son": Thoreau Lionett Jr. Beau herself took the letter to mean her parents no longer wanted any contact with her.[63] She assumed they were no longer going to pay the Cobalt Soul to train her and thought she would be doing the monks a favor by leaving.[64] And so she did so, abandoning the Valley Archive to pursue her own ends.

Beauregard's parents, Thoreau and Clara Lionett, were in the wine-making business in Kamordah. Beau was made to manage the bookkeeping. As the winery's most frequent customers were halflings, Beau learned the Halfling language as a result.[56]

She mentioned to Bo "The Breaker" that her name was Beauregard because her parents wanted a son.[57]

Beau thought little of her father as she grew up. Although Thoreau was not violent, she found him "standoffish and distant"[58] and his paranoia, born from his conversation with Isharnai, led to him restricting her freedoms and underestimating her capabilities. Possibly out of a desire for revenge or an attempt to force her parents to notice her, Beau began to steal and resell his wine at a mark-up. This led to her committing other crimes, including extortion and trafficking. While playing a game of chance with Molly, Beau revealed the best lie she ever told was when, not liking a politician and his wife in the town she grew up in, she worked as a house hand for them as a means to dig up dirt on them. She found out that they were each cheating on each other, causing them to break up when she exposed the information.[59] One of Beau's criminal associates was a woman named Tori, whom she was also romantically involved with. When Beau and Tori were arrested together, Beau's father Thoreau Lionett attempted to bribe Tori to agree never to see Beau again, and when Tori refused, had her sent to Zadash for trial and punishment. He told Beau that he had paid Beau's bail but not Tori's, and Beau never learned what happened to Tori after that.[60][61]

Beau gained the meta nickname "The Disaster Lesbian"[54] due to how often her flirtations with other women failed to succeed. Notably, she called Expositor Dairon "very attractive" as soon as she saw the elf without their concealing cloak, she made near constant advances on Yasha early in the campaign, and she has expressed romantic interest in Jester. Later she admitted this crush being "transferred" towards Jester because she was fun and easy to fall in love with. After Yasha's return, Beau's flirting was reciprocated, and she admitted to Fjord that she's always had a thing for Yasha that was "something of more sustenance, that is not as fleeting" as her feelings towards Jester. Beauregard's hiring of a female courtesan at The Landlocked Lady in "Converging Fury" (2x27) and her sleeping with Keg in "The Journey Home" (2x30) and Reani in "Refjorged" (2x76) showcase her attraction to the same sex. That said, though, Beau often saw herself having intimate relations with other women as being a "band-aid". And according to Marisha's second playlist for Beau, a lot of those "disastrous" vibes she gives off are a front designed to hide how utterly terrified she is of ending up alone, and that she's been lucky in lust yet unlucky in love.[55]

Marisha described Beau as a simple girl with simple needs.[44] Beau's attitude towards other people can be summed up as "do whatever you want, but if it fucks with my shit, we're going to have issues."Beau has few concerns when it comes to violence, having demonstrated a willingness and, occasionally, an eagerness to harm others if it serves her interests. This aggressive attitude, along with her general dislike of authority figures,[46] put her at odds with her superiors in the Cobalt Soul.[47] This attitude has extended to other party members who tried to commandeer a situation Despite having above-average Charisma, Beau is particularly abrasive in ordinary social interactions, frequently coming off as insulting when she tries to give compliments[49] and straining credulity when she attempts to be polite. In order to improve her social skills, Fjord suggested that she smile more, but due to Beau's usual hostility, her smiles tend to come off as either unsettling or extremely disingenuous.In higher-stakes dealings with strangers she frequently peppers her speech with lies—she is better at deception than persuasion—sometimes with positive results.She is intelligent (much more so after getting a Headband of Intellect) and talented at investigating, but with unlucky streaks. She is knowledgeable about history (a testament to her Cobalt Soul training), and though she often downplays it as "just something she happened to learn while doing so-and-so," she keeps thorough notes. Beau is ambivalent about learning: she acts dismissive of nerdy book studies, but she privately studies and is hungrier for knowledge than she is willing to admit even to herself.Beau was one of the first of the Mighty Nein to come out of her shell and consider herself a true friend to them, saying she would lay down her life for them.

At the start of the campaign, Beau wore baggy clothes and monk vestments in shades of blue and gray. She had a blue sash around her belt with embroidered script from the Cobalt Soul written on the interior in the backside. Her long dark-brown hair was tied into a topknot. While in Zadash, she customized her long sleeveless coat to be able to turn it inside out, having it cobalt blue on one side and a normal brown on the other. She later acquired brown-black, jagged leather boots embedded with studs with two spikes at the tip, as well as a set of studded leather glove-like gauntlets.During her time in Felderwin, she also bought a belt with extra pockets to store her money in.
