Gavin Banks is a member of the Assassin Order, stationed on a boat named the Altair II, which roams the Pacific Ocean. He keeps in communication with Assassin teams that operate around the globe, and monitors their progress on a daily basis. After William Miles' team broke their silence, the latter transferred his position as Assassin leader to Gavin.
Roaming the seasEdit
On 10 September 2012, Gavin was contacted by an Assassin operative who called him from a public phone in Brisbane, Australia. The caller told Gavin that it had been three days since he had last heard from his team, and that they had failed to report again. As Gavin was giving instructions to the caller to quickly pull out of the area, the telephone signal was interrupted. At some later point, Gavin himself confirmed that the whole team in Brisbane had been eliminated.
Two days later, on September 12, Gavin received a call from an operative named Janice, who was a part of an Assassin team in Whistler, Canada. During their conversation, Janice demanded that Gavin send additional manpower as she had only two operatives with her. He replied that he would see what he could do, but this proved to be a moot point when, at that moment, Templars led by Daniel Cross attacked the Whistler team.
Weeks later, on October 5, Gavin called William Miles via cellular phone. He updated William about the status of the Assassin teams in Brisbane, Osaka and Moscow. In turn, William, who was in Italy, briefly informed Gavin of the favorable progress the Assassins were seeing at his end.
Traveling in AmericaEdit
On 24 October, Gavin received a coded message from Adriano Maestranzi, which instructed him to head to New York, and also that William should be making contact with the Order soon. Two days later, Gavin met with William's team at an airport in Syracuse, New York, where he provided them with fake documents which allowed them safe passage into the state.
Gavin then began traveling around the United States, attempting to draw the Templars' attention away from William's team. On 2 November, Gavin sent William a text from Stillwater, Oklahoma, informing him that the Templars had no clue where they were. The next day, he sent another text to William from New Orleans, updating William on the status of the Assassin team in Florence, which had lost a member.
Back at seaEdit
On 4 December at 6:09am, Gavin and his crew picked up William's team from Vitoria Bay, Brazil, after they had recovered a First Civilization artifact. Two days later, Gavin and the Altaïr II were on the South Atlantic ocean, just off the coast of Brazil, when he received a text message from William at 9:32pm. In the message, William thanked Gavin for the ride, and also included that his team had safely returned to the Grand Temple without the Templars following them.
On 6 December, Gavin sent a text message to William which informed him that the Assassin Order had identified the Templar responsible for initiating an attack on the Florentine Assassins as Juhani Otso Berg, an ex-special forces soldier from Finland who had become a mercenary a few years ago. He remarked that Berg was a serious threat, but that Adriano had managed to scar him before he died. William responded by thanking Gavin for the information and told him that they would be on the watch for Berg.
On 19 December at 9:12pm, Gavin received a call from Harlan T. Cunningham, the only survivor of the Florentine Assassins. Gavin was relieved to learn Harlan had made it safely to a safe house in Vienna, Austria, and expressed his sympathy regarding Adriano's death. He also reassured Harlan that it was not his fault that the other Assassins had died, before instructing the Assassin to go to Rotterdam in the Netherlands and wait for further orders, adding that Harlan take it easy until then.
On 20 December at 6:13pm, Gavin got a text from William that his team had found the Grand Temple Key and were heading back to the Grand Temple to open it. Gavin congratulated him and said that he would pass the news onto the other Assassins.
Leading the BrotherhoodEdit
William and his team successfully opened the Grand Temple and prevented the Second Disaster, but at the cost of Desmond Miles' life and releasing Juno upon the Earth. Gavin was not contacted by them for nearly six months, until on 14 May 2013 he received a text from Shaun Hastings with a coded message to pick them up in Peru. Gavin and his team sailed there, meeting with Shaun and Rebecca Crane on 21 May, and they gave him a book and letter from William.
The letter informed Gavin that William was leaving the Order, and that he had written all his knowledge down in the book for Gavin so that he could lead and rebuild the Assassin Brotherhood. William apologized for dumping this burden on him, but made clear that his decision to leave was final.
On 24 May, Gavin was asked by Shaun what he was going to do about William, but Gavin felt there was nothing they could do but wait for him to sort out his issues by himself, and that he doubted the Templars would be able to find him if Shaun had failed to do so. Shaun wondered what they would do now, and Gavin informed him they would move on with their work.
Over the next few days, Gavin and his crew made improvements to the Altair II while sailing north. On 29 May, they reached California, where Gavin asked Shaun and Rebecca to be his eyes and ears in America and keep him apprised of any Templar or Abstergo activity. He received several updates from Rebecca over the next few months, and on 27 August, Rebecca e-mailed him from Oklahoma City, saying that she and Shaun had decided to try and locate Desmond's body or discover what Abstergo had taken it for. On 3 September, he received another e-mail from Rebecca, who expressed concern over the amount of resources the Templars were putting into Abstergo Entertainment.
On 11 September, Gavin and his team stopped in Honolulu Harbor. Susan Drayton wondered why they were not in Osaka yet, and Gavin expressed concern over the fact that his former Mentor Kenichi Mochizuki, the leader of the Osake Brotherhood, had not contacted him. Eric Cooper noted that all of their communications had gone down in December, but Gavin informed them that he and Kenichi had their own way to communicate. Susan was worried about sailing into a trap, but Gavin reassured her they would not fall into it and ordered Eric to set sail for the Philippines, and that they were going to go "shopping". By 1 October they had bought weapons from arms dealers there, which Emmanuel Barraza inspected.
On 11 October, Gavin read an article about Abstergo Entertainment's Montreal studio which included a statement from its Chief Creative Officer, Olivier Garneau. Gavin e-mailed Rebecca and questioned who Garneau was and wondered what he might know.
On 2 December, Rebecca e-mailed Gavin about the death of their Abstergo mole, John, and that she and Shaun planned to leave Montreal soon. He wished them luck, sent his greetings to William, and informed her that he would make another attempt at reaching Osaka.
Mission to JapanEdit
Gavin and his team arrived in Osaka on 4 December, and he took Emmanuel and another Assassin to the headquarters of the Osaka Brotherhood. They discovered the Assassin cell had been attacked, and Gavin used his Eagle Vision to determine that the Yakuza, not Abstergo, had killed one of his first mentors, Kenichi Mochizuki, and several other Assassins. He ordered his team to search the city for any Assassins that survived, along with the Yakuza who had carried out the attack.
The crew of the Altair II gathered much information over the next nine days. Emmett learned that a particularly ruthless branch of the Yakuza known as the Onmoraki-Gumi had supposedly been wiped out recently in a violent gang war, but their business fronts were still operating. Emmanuel tracked a financial transaction to the Onmoraki-Gumi's new base, but no one on the team was able to learn the identity of its new leader. On 13 December, Gavin decided that they would confront the Yakuza directly to learn what they needed.
On 17 December at 9:47pm, Gavin took Emmanuel with him to the headquarters of the Onmoraki-Gumi to demand a meeting with their head, intending to try and get inside their heads like Kenichi had once taught him. They were confronted by a guard who introduced himself as Kiyoshi Takakura and threatened to beat them if they did not leave. Gavin refused and insulted Kiyoshi's fashion sense, which resulted in Kiyoshi attacking Gavin. He was knocked to the ground as Kiyoshi began kicking him, and Emmanuel was unable to help as he reminded Gavin he was a pacifist. Several other members of the Onmoraki-Gumi emerged to watch the beating, which allowed Emmanuel to overhear them discussing how "Grandma" would not be happy with this due to how hard she had worked to hide the Brotherhood. Gavin's life was then saved by Emmanuel, who stuck his hand in front of Kiyoshi's Hidden Blade and then stopped the beating by revealing he and Gavin were Assassins.
At 1:03am the next day, Gavin and his crew were taken to meet Saeko Mochizuki, the Mentor of the Osaka Assassins and wife of his former mentor Kenichi. Gavin learned that she had taken over the Osaka Brotherhood after the Onmoraki-Gumi had attacked them and Kenchi was killed, and had led the Assassins in killing the Yakuza branch's leaders and taking it over, claiming it was a good fit due to the two organizations shared history of working in the dark and assisting the common people. Gavin was not pleased by this development, but kept his criticism to himself.
Over the next two days, Gavin exchanged information with Saeko. After learning that the Osaka Brotherhood was low on supplies from their recent struggles, Gavin gave them the guns his cell had bought from the Philippines as well as the contact information for their supplier there. He was then given a new type of Animus headset that Saeko's team had stolen from an Abstergo Industries facility, and Saeko told Gavin that she feared the Templars were planning something big.
On 23 December, Gavin complained to Dr. Stephanie Chiu that she was fussing over Emmanuel's injury while he had been left to treat his own wounds by himself. Stephanie told him that he should not have picked a fight with a trained Yakuza Assassin half his age, but Gavin angrily reminded her that he would not have had to do that if Emmanuel had done his job. Gavin felt somewhat guilty about forcing the pacifist Emmanuel into situations that would need violence, and declared that the team needed an enforcer.
On 31 December, Gavin and the crew of the Altair II traveled to Tokyo with Saeko and Kiyoshi to gather supplies for their next mission. As the rest of his team preoccupied themselves across the city, Gavin ran across the rooftops of Tokyo to deal with his stress, and watched from a rooftop as fireworks were fired off at midnight to celebrate the new year.
Gavin decided that with the Assassin presence in Japan secure, it was time for his crew to move on. The Altair II left Japan on 15 January 2014, and Gavin turned to another riddle in William's codex to determine their next destination. Emmett questioned why they did not simply contact William, who had returned to the Assassin Order, but Gavin informed him that he was not aware where William was at the moment or how to get in contact with him. He added that this was their own mission to figure out, and that it would not be any fun to have all the answers from the start.
While Gavin demonstrated the use of Eagle Vision to discover the fate of the Osaka Assassins, one of Gavin's men noted that it didn't come natural or as easy to him, and that he looked tired after using it. This revealed that Gavin may not have the ability through natural means, rather gaining it through training, or that he had an innate, but low aptitude for it.
He was also shown to be a capable free-runner, as he traversed the rooftops of Tokyo to deal with pent-up stress.
- Gavin had known William Miles for many years, and affably called the Assassin leader "Bill", who in turn referred to him as "old friend".
