Beranger is the eldest of three children from his father's first marriage and has always been protective of his two younger sisters. Weathering the second Sabbat Civil War with them, he grew discontent very early on with his expected role in the Lafayette household and so decided to answer a call for help from the New Orleans Sabbat in the midst of their war with the Brujah. Leaving his two sisters to their unhappy arranged marriages, he went to New Orleans and set himself up in the business which came most naturally, tending to carnal desires. Working with Setite agents, he established himself as a trader in flesh and a purveyor of forbidden pleasures. His deft use of the resulting capital and blackmail material greatly aided the Sabbat cause throughout the years and he gained even more favor from his family when he discovered the lost sheep Joseph and returned him to the fold.
Beranger never forgot his sisters and visted frequently, helping them through the rough periods in their marriage and acting as confidant, friend, and, often, lover. The death of his sister, half-brother, and father during the 1970 raid hurt him deeply. Embroiled in the final battle with the Brujah, he didn't even hear of it until it was too late and he still blames himself for not being there. To add salt to the wound, the resultant domination of his remaining sister by Marie-Thérèse has destroyed her mind, leaving in him a deep and abiding hatred of the matriarch. He has since taken to helping his younger sister's daughters marry outside of the family or at least marry into branches of the Prejean family not in Lafayette, to spare them the same fate. He realizes that Émeline will cease to be of any use to the Tzimisce elder soon and doesn't want to see another share the same fate. Unfortunately, he has been unable to do anything about Émeline's eldest, Jocelyn, who is also favored by the matriarch and seems the perfect candidate to replace her mother.
The futility of his efforts on Jocelyn's behalf has led to a new approach. He has taken to trying to turn the Prejean kindred against the matriarch. Thus far, he has only managed to have any success with Joseph, with whom he has the closest relationship, but he has managed on one occasion to even bring his concerns to Jean-Michel, though he is unsure of the elder's inclination.
Were he not a revenant, Beranger might be a fine person. Unfortunately, his compassion and sensitivity are twisted by his upbringing and heritage. He honestly believes that he is helping the slaves he sells to rich sadists and the children he provides to pedophiles by bringing them to know the closest real thing to love available in the material world. Philosophically incapable of separating physical and emotional feelings, he is a perfectly sincere sexual predator, which makes him all the more dangerous and compelling.
Not manipulative by nature, his seductive skills are based instead on this perfect frank sincerity and the passionate belief in his twisted perspective. He is also highly emphathic and has a knack for latching onto the physical and emotional needs of those he interacts with, a skill which has helped him match predators and prey throughout his career in the sexual underworld.
Beranger's closest friend is Joseph, due to the deep similarities in their mindsets. The two spend a lot of time talking and support each other implicitely. It is also helpful that Beranger provides Joseph with young boys to molest and is provided with philosophical rationalizations for his own behavior in return. They also share their concerns about the family and agree that something needs to be done to curb some of its harmful excesses.
He is also on fairly good terms with the other Albigensians in the city, regardless of their clan. His willingness to listen has made him something of a father confessor for many of them and this has also made him privvy to a number of their secret concerns and ambitions, though he generally keeps such things to himself or shares them only with Joseph.
Back home, he has grown distant from most of his family. He has a vague dislike for his brother-in-law Gerard, mostly because he failed to prevent Emily's mental deterioration but also due to the circumstances of their marriage. He doesn't really understand Uncle Rodolphe and so tends to avoid him more than anything. He is deeply devoted to Ida and Emma, as the children of his dead sister, and is even fond of Emma's husband and their child Sevis, but feels distanced from them by his guilt over Henrietta's death. However, he does support them whenever possible and tries to disuade the fighting between Ida and Emma that has grown so apparent in the last few years.
He is deeply respectful of the kindred of Lafayette with the exception of Marie-Thérèse and makes a point to visit with them whenever he is back home, telling them of affairs in New Orleans and asking their advice on how to proceed. He is particularly fond of Father Sicard and takes heed of his advice, practical or philosophical, whenever the quiet elder chooses to dispense it.
He also has a deep infatuation with his cousin, Constansa, in Biloxi. The two have been romantically involved at several points in their lives and he tries to get away to visit her whenever he can (which is still rarely, given his obligations in the city and to his family). He secretly suspects that Raoul may be his son, but hasn't pressed the issue.
Beranger has significant influence in the underworld, both due to his money and his reputation. His connections with the black market trade (run by the Serpents) also make him the man to know if you need contraband. His specialty is people, but he's also been known to get exotic drugs, aphrodisiacs, and other rare indulgences from abroad.
