Later, Aveline went to the family warehouse at the request of Gérald, but encountered a commotion along the way. Rebelling against their new masters, a group of civilians had gotten into a fight with Spanish soldiers, leading Aveline to step in. After she saved them from the better-armed soldiers, Aveline spoke with the rioters and learned of the number of slaves and vagrants that had vanished since the arrival of the Spanish.
Unsettled, Aveline continued on her way to the warehouse, where she discovered that Gérald had turned it into the Order's new headquarters, making room for her weapons and guises. She was also given a special parasol that functioned as a dart gun, following which she was informed of a business rival, monsieur Bouché, that had been slandering the de Grandpré's reputation. With the business' sales already dropping, Aveline quickly set out to cut Bouché's campaign of lies short.
Threatening Bouché into submission, Aveline saw his bankruptcy as an opportunity to provide his slaves with honest, better-paid labor and bought one of his shops. She then returned to her headquarters, where she discussed the increase in kidnapped slaves with Gérald and decided to travel to San Danje to investigate. There, she consulted the houngan, who advised her to speak with her friend Élise, a frequent employer of San Danje's denizens.
Doing so, Aveline found out about the convoys of slaves that were departing from Fort Saint-Jean, a fortress occupied by the Spanish. Aided by Élise, the Assassin attempted to uncover where the workers were headed, first intercepting a convoy and then infiltrating the fort itself. Despite their efforts, the pair discovered little information, apart from the fact that the slaves they had liberated were strangely upset at not being able to board the work ship that would transport them to their destination.
Back in New Orleans, Aveline met with Gérald and voiced her frustration about failing to find out where the slaves were going, even though she had confirmed the involvement of the Spanish. Gérald posited the directive must have come from governor de Ulloa and offered to help Aveline in drawing him out of La Balize, where he had hid since coming to Louisiana. The two Assassins then went to the Place d'Armes, where Aveline, disguised as a slave, used the tense crowd to incite a massive riot.
While the French citizens rioted against the soldiers, Aveline and Gérald intended to cause further disturbance by stealing a gunpowder-laden carriage. After quietly eliminating the guards, the pair took control of the rig, but were spotted and fired at upon their departure. With the docks as their destination, Aveline and Gérald rode at high speeds through the cluttered streets of New Orleans, but found their carriage to be set on fire en route.
Forced to abandon their ride, the pair watched as the rig crashed into a wine storehouse, causing a huge explosion. Noticing civilians being trapped inside by Spanish soldiers, Aveline entered the burning building and killed the soldiers, so that the civilians could escape. Afterwards, Aveline and Gérald decided to regroup at the warehouse.
The Assassins quickly hatched another plan, targeting two Spanish military vessels that were anchored at the docks. After Aveline took out the guards aboard one of the ships, she planted some explosives, but was interrupted before she could set them to detonate. Carlos Dominguez, this time sober enough to recognize her, ordered his men to stop her, though they posed little challenge to the Assassin. After warning Dominguez to save himself, Aveline activated the explosives and swam back to the shore, from which she watched the vessel being destroyed.
As the Spanish governor finally prepared to leave La Balize, Agaté called Aveline to Saint Peter's Cemetery, where he gave her the order to kill de Ulloa, to prove her loyalty. Aveline then set up an ambush, barricading several streets so that the governor's convoy would march into a blocked off town square. By blowing up a powder keg, Aveline took out the majority of de Ulloa's soldiers and, after finishing off the survivors, forced the governor out of his carriage. Upon interrogating him, the Assassin learned that the slaves taken from New Orleans were being transferred south, to a work camp in Mexico.
Against Agaté's orders, however, Aveline chose not to kill de Ulloa, allowing him, and his pregnant wife, to flee the city in return for a lens used to decipher encoded Templar documents, a map leading to the work site at Chichen Itza and the promise of de Ulloa to go into exile. This merciful act continued to harm Aveline's already damaged relationship with her Mentor. He subsequently forbade her to travel to Chichen Itza, but Aveline ignored this, receiving a warning from her Mentor that she would live to regret her insubordination.
Aveline then went to depart for Mexico, but was met by Gérald before she could do so. Worried for her, Gérald confessed how much she meant to him, but ultimately realized there was little he could do or say to make her stay. After being given some last advice, Aveline handed Gérald her weapons for safekeeping and thanked him for his aid, before leaving to join a group of slaves that would board a ship bound for Mexico.
Arriving in the ancient Mayan city of Chichen Itza in 1769, Aveline discovered the excavation site was being supervised by de Ferrer and listened to one of his welcoming speeches. Afterwards, she mingled with the people at the camp, in order to unravel the mysteries of her new surroundings. To her surprise, she encountered Thérèse, the slave Aveline had rescued from captivity about four years ago, who, along with various other slaves, seemed to be perfectly happy at the worksite. Before continuing her investigations, Aveline collected material around the camp and crafted two makeshift Hidden Blades to defend herself.
Now sufficiently armed, Aveline sought out de Ferrer and followed him to a meeting with the camp's overseer. There, she overheard that not all workers were enthusiastic about their situation, with a few even attempting to escape. Tailing them, Aveline was led to one such slave, who was to be "educated" for his mistake. After de Ferrer left, the overseer and his guards attacked the captive, but they were killed by Aveline before they could hurt him.
After taking out additional reinforcements with the overseer's whip, Aveline talked to the runaway slave, who spoke of a woman named Jeanne that had been stationed at the camp. Convinced it was her mother, the Assassin scoured the work site for clues, finding evidence that her mother had indeed been there at some point. Among pages found from Jeanne's diary, Aveline discovered a map detailing the location of an ancient artifact deep within a nearby cenote.
With this in mind, Aveline traveled to the cenote's entrance, navigated the underground cave system and uncovered ruins from the First Civilization. There, she solved a puzzle that functioned as a defense mechanism, causing a fragment of the Prophecy Disk, an ancient artifact, to be revealed. Moments after obtaining the relic, Aveline was met by de Ferrer, who had reached the ruins by blasting through a rock wall.
Intending to steal the artifact, de Ferrer and his guards engaged Aveline in battle, though she killed them all, with de Ferrer himself being thrown into the depths of the cavern. The Assassin then quickly made her escape, as the cave was rapidly collapsing due to de Ferrer's explosives. Having reached a safe area, she happened upon her mother, Jeanne. However, this reunion was short-lived, as Jeanne, realizing that Aveline was an Assassin, believed Agaté had sent her daughter to come and kill her. Refusing to disclose any information, she then fled the mines, leaving Aveline with more questions about her Mentor.
After her escapades at Chichen Itza, Aveline returned to New Orleans in 1771 and continued her search for the identity of the Company Man. Heading to the warehouse, she reunited with Gérald, who informed her that the Spanish had put new laws in place during her absence, which would ease their efforts in helping the slaves. Despite this, a rogue faction of Spanish troops had also sprang up and was raising havoc in the bayou. Having gotten back her weapons, Aveline set out to chase down a lead, a recruiter that was bribing guards, in the hopes of uncovering who these soldiers were working for.
Finding the recruiter, Aveline then tailed him to a meeting with two Spanish soldiers, who had agreed to join the recruiter's cause. As she neared to apprehend him, the man spotted her and took off, with the Assassin quickly giving chase. Despite her efforts, the recruiter managed to reach the city's fort and hid within its walls, prompting Aveline to then infiltrate it.
Locating the man with her Eagle Vision, Aveline followed him to a quiet spot within the fort, where she eliminated him. Aveline then looted the recruiter's corpse, finding a message from his employer. After escaping the military barracks, Aveline read the letter and discovered that a man by the name of Vázquez was using the bribed troops to seize control of the bayou. Fearing he would eventually learn the location of Agaté's hideout, Aveline hurried to the bayou to warn her Mentor of the danger.
Upon her arrival there, she found the hut empty, leading her to track Agaté down, who was less than pleased to see her and grew even more bitter when she presented him with a piece of the Prophecy Disk. After some bickering, Aveline agreed to hide the fragment, following which she attempted to warn Agaté of the new threat. Her Mentor then revealed he was already aware of Vázquez's troops and begrudgingly accepted Aveline's offer to help him.
Upon hearing his plan, Aveine doubted it would put a permanent stop to Vázquez's efforts, but nonetheless carried it out. By silently poisoning enough of the troops as they passed the voodoo signs set up by Agaté, Aveline made the survivors believe they had fallen under a curse, causing them to flee. She then journeyed to the headquarters of her smuggler allies.
There, Aveline spoke with Élise and Roussillon, who confirmed that they too had noticed the increase in Spanish troops. Upon mentioning Vázquez, Roussillon informed her that the Templar was attempting to divert a supply ship for his own purposes. In response, Aveline disabled the lighthouse on Lake Pontchartrain, causing the ship to run aground on a nearby island.
Afterwards, Aveline and the smugglers traveled to the trapped ship, intent on stealing its supplies. Defending her allies from Vázquez's guards as they transported the cargo, the Assassin was disappointed upon discovering that Vázquez himself had not been on board. However, among the supplies that the smugglers had stolen, Roussillon found documents containing orders to reclaim the worksite in Chichen Itza, leading Aveline to hurriedly journey back to Mexico.
In 1772, Aveline arrived in Chichen Itza to ascertain whether or not her mother's safety had been jeopardized, as well as to locate the missing half of the Prophecy Disk. To Aveline's surprise, her mother, having decided her love was stronger than her fear, was no longer afraid of her and greeted her warmly. Having made peace with one another, Jeanne then asked her daughter to retrieve the second piece of the artifact, so that she might finally be free from the prying eyes of the Templars.
Aided by a map from her mother, Aveline found her way to a lone canoe that would allow her to navigate the cenote's rapids. After abandoning her mode of transportation, Aveline explored the underground cave system, eventually happening upon the entrance to another chamber constructed by the First Civilization. There, she solved the puzzle to an ancient defense mechanism, which allowed her to acquire the final piece of the Prophecy Disk.
Afterwards, Aveline returned to her mother with the artifact and offered to take her back to New Orleans. However, Jeanne decided it was best to stay behind and take care of the community in Chichen Itza, which had been freed of Templar influence, thanks to Aveline's intervention. Promising to remain in contact, Aveline then returned to New Orleans.
Having returned to New Orleans, Aveline found that her father had become bedridden due to an illness. Despite her worries for his health, she continued her quest to uncover the identity of the Company Man, infiltrating slave trader organizations and, with Gérald's help, expanding her network of contacts. During one of her visits to her father in 1776, Aveline was called upon by Madeleine, who asked her to help a slave named George escape New Orleans.
Carrying out her stepmother's request, Aveline sought out George and, after saving him from a couple of guards, escorted him out of the city. She subsequently contacted her smuggler allies, in the hope that they could provide George safe passage through the swamp. Although Élise and Roussillon were not opposed to the idea, as they were also tasked with delivering supplies from the Spanish to American Patriots fighting in the Revolutionary War, rogue Spanish soldiers were once again opposing their activities.
Seeing an opportunity, Aveline decided to help Élise and Roussillon in transporting their wares, so that they might convince the Patriots to take George to the North. Navigating the bayou's trees, the Assassin, aided by musket fire from George, took out the Spanish troops before they could inflict damage on the smugglers' raft. As a result, Élise and her men managed to safely reach their destination, where they met with Hopton and the other Patriots.
After the goods were transferred, Aveline discussed the Spanish attacking them, prompting Hopton to mention Vázquez, who hadn't been very keen on the arrangement between the revolutionaries and the Spanish governor. Surprised to hear that he was back in New Orleans, Aveline decided to resume her hunt for the Templar, believing him to be the Company Man. Before leaving, she asked the Patriots if they would allow George to accompany them to the North, to which they agreed, provided he fight for their cause.
From there, Aveline returned to New Orleans and spoke with Gérald, hoping to learn more information on where to find Vázquez. However, several of Gérald's informants had been recently poisoned by the Templar's men, giving the pair little to go on. They decided to attend the Capitán's Ball, a prominent soirée held at a luxurious plantation, in the hopes of finding Vázquez there.
Mingling with the guests, Aveline managed to locate Vázquez using her Eagle Vision and approached him under the pretense of wanting to dance. After charming the Templar, the Assassin led him to a quiet balcony away from the party, where she then assassinated him. With his dying breath, Vázquez revealed that he was not the Company Man, with Louisiana's head Templar being, in fact, a woman.
Unsure of what to do with this information, Aveline went to leave the party, but found Madeleine waiting for her at the plantation's gates. After receiving a scolding, she learned that her father, whose illness had worsened despite her stepmother's tonic, had passed away during her absence. Shaken, Aveline later met with Gérald and Madeleine at Philippe's grave in Saint Peter's Cemetery. Although she cared little about her lack of inheritance, Gérald assured her that he considered the de Grandpré business to be hers, even if it had officially been left in his name.
Feeling defeated, Aveline's resolve to discover the identity of the Company Man nevertheless stayed strong. However, without any leads, she struggled to find a trace of the Templar. Thanks to Gérald being in contact with the Colonial Assassins, Aveline learned of a Loyalist officer named Davidson, who was working for the Company Man, and subsequently headed north to find him.
Arriving in the winter of 1777, Aveline met up with her Assassin ally Connor, who had agreed to aid her, in the New York Frontier. After catching and interrogating a sentry, the two Assassins discovered Davidson was based in a nearby fort. They then made their way to the stronghold, battling various Loyalist troops along the way, before deciding to split up.
While Connor distracted Davidson's guards, Aveline discreetly infiltrated the fort and confronted the Templar in the watchtower. To her shock, she discovered that his true identity was George, the slave she had helped flee north the year before. Questioning her motivations for coming to New York, the Templar and his men then engaged Aveline in battle, though she easily dispatched the latter. However, a sudden explosion, set off by Connor, caused George to flee, locking Aveline inside the watch tower and forcing her to climb all the way up and escape through the broken roof.
Despite the obstruction, Aveline managed to foil George's escape, blowing up the wagon on which he attempted to flee and mortally wounding him. Regretting the outcome, Aveline asked George who the Company Man really was, prompting him to say the "answer had been in her own backyard all along", before he succumbed to his injuries. Shortly thereafter, Aveline spoke with Connor on the Assassin Brotherhood's means and ways, her own belief in the cause having faltered due to recent events. Receiving the advice to "trust her own hands", Aveline then returned home with a heavy heart.
Having realized that the Company Man had been none other than her own stepmother, Madeleine de L'Isle, Aveline went to the family mansion and confronted her. Madeleine did not deny her accusations and admitted that she had known all along that Aveline was an Assassin. Furious, Aveline refused Madeleine's order to stay and ran outside, but was quickly intercepted by her stepmother's guards.
Brandishing her parasol, Aveline waited for Madeleine to reappear, who attempted to dissuade her stepdaughter from further resistance and lamented the fact that they had to argue. Following this, Madeleine insisted that she genuinely loved Aveline, especially since she wasn't able to bear children herself. She continued, stating that Aveline had been kept alive in order to eliminate the unethical elements of her Templar circle, such as de Ferrer. Pointing to the broken relationship between Aveline and her Mentor, Madeleine argued that their aims were the same and asked Aveline to join the Templar Order, to "finish what she started".
After this, Aveline journeyed to the bayou to seek Agaté's counsel and test her own faith in the Brotherhood. However, her Mentor could not accept his failure to protect his student, and, believing that Aveline had aligned herself with the Templars, attacked her. Having a bomb filled with poisonous gas thrown at her, Aveline unwittingly inhaled the vapors and subsequently began to hallucinate, believing she was being assailed by the Templars she had slain.
Even so, Aveline eventually realized she was fighting against mere, poison-induced illusions, and ascended the treehouse, attempting to get through to Agaté. However, her Mentor refused to listen to reason and, when cornered at the top of his treehouse, bitterly lamented that he should have stayed with Jeanne. Refusing to listen to his raving any more, Aveline angrily told Agaté to leave Louisiana and never return. Unable to live with the humiliation, he dove from the platform, to his death.
Traveling back to New Orleans, Aveline went to the Saint Louis Cathedral, where she gave Agaté's necklace, which she had obtained when she unsuccessfully attempted to save him, to Madeleine, as proof of his death. Madeleine then asked for the two halves of the Prophecy Disk, before inducting Aveline into the Templar Order. However, upon the artifact failing to work as Madeleine had expected it to, she grew frustrated, allowing Aveline to strike, as her induction was merely a ruse to destroy the Templars from within.
Aveline assassinated all of the Templars present, leaving Madeleine for last. As she lay wounded, Madeleine asked her "daughter" why she would betray her as she had. Aveline coldly retorted that she had two parents whom she truly loved, and that Madeleine was not one of them. She then blamed her for killing her father with her "care" and her tonic, secretly foxglove, for enslaving her mother, and for her intention of making Aveline a slave to the Templar cause.
To this, Madeleine insisted that it was for the greater good of humanity, as work had always been the "divine purpose" for which they had been created. In response, Aveline defiantly claimed that she would never be forced to serve another and assassinated Madeleine afterwards. Following this, she recovered the Prophecy Disk and used the locket her mother had entrusted her with to activate it. Aveline then witnessed a hologram of beings from the First Civilization, who briefly spoke about electing Eve as the official leader of humanity's rebellion against their creators.
