The Louisiana Brotherhood of Assassins, also known as the Assassin Brotherhood of New Orleans, was a Guild of the Assassin Brotherhood founded by the Assassin Mentor Agaté after the death of his own Mentor, François Mackandal, and the collapse of the Saint-Dominigue Brotherhood. Their primary goal was to eliminate Templar control in the colonies of New Spain, but Agaté's relocation was mainly motivated by his hunt for his former lover Jeanne, who had stolen the Prophecy Disks from him and found refuge in New Orleans.
In 1758, after the execution of the Saint-Dominigue Brotherhood's Mentor, François Mackandal, by the Templars, the branch nearly dissolved. In the wake of this defeat, one of Mackandal's apprentices, Agaté, left Saint-Domingue in pursuit of his former lover, Jeanne, who had stolen the prized Prophecy Disks from him. Having learned that Jeanne had settled in New Orleans, he arrived in Louisiana, only to lose track of his quarry as Jeanne had speedily fled Louisiana upon hearing that Agaté was nearby. Since Jeanne had a daughter, Aveline de Grandpré, who she had left behind, Agaté decided to stay in New Orleans to protect her. In 1759, Aveline, who got in trouble after rescuing slaves, was saved by Agaté. Seeing Aveline's potential and her desire for justice and freedom, Agaté took her as an apprentice and inducted her in the Assassin Brotherhood after months of training. The same year, Gérald Blanc, a friend of Aveline, was also recruited by Agaté to serve as a spy and a logistician for the brotherhood. They then established a network of servants through the city to uncover the Templars' schemes.

With their help, she discovered that Mackandal prepared a sacred ceremony at the Eve of Saint John. The Houngan of San Danje gave her the localization of the ceremony but also an antitode to Mackandal poison. At the ceremony, Aveline uncovered the truth: Mackandal was in fact Baptiste, a former Assassin and apprentice of Mackandal, who worked for de Ferrer. Baptiste planned to poison the nobles of New Orleans to avenge the death of the slaves of Saint-Domingue and also to be inducted in the Templar Order. Aveline engaged Baptiste but she was poisoned by the former Assassin. Thanks to the antidote of the houngan, Aveline survived and killed Baptiste.

But Aveline spared Ulloa's life and the Templar gave her the information that the slaves were brough to a work camp in Chichen Itza and also a lens used to decipher encoded Templar documents. After revealing to Agaté she spared Ulloa, the Mentor forbade her to go to Mexico, but Aveline ignored his order and embarked as a slave in a Templar ship to Chichen Itza.
