My'shell Lemair is a member of Erudito and one of the new field agents trained after the reorganization of the hacker collective in 2016. She later joined the Assassin Brotherhood, being trained by Galina Voronina.
Erudito field agent
At some point before 2016, My'shell joined the Erudito collective, an organization of hackers and truth seekers operating on the web.
After the collective discovered that the Templars's Phoenix Project was infitrated by the Instruments of the First Will, who wanted to use it to create a new body for the nefarious Juno, Erudito's leader, Florencia, decided to reorganize the collective toward a more militant way. To do so, she decided to cut with Erudito's rule of staying in the shadows and My'shell voluntered to be trained as one of Erudito's new field agents.
Alliance with the Assassins
Acting as the sparring partners of a recovering Galina Voronina, My'shell and Sheed received additional training from the skilled Assassin in the Argentinian complex of Erudito. Following the formal alliance between their organizations, the two operatives were sent with Voronina to capture the rogue Assassin Joseph Laurier in Somalia.
Once in Somalia, the team infiltrated a inauguration ceremony attended by Zerha Okur, a local Templar, after they discovered that Laurier was in the country to kill her. Using a facial recognition software, the team waited for their prey but instead were fooled by the experienced Assassin. Indeed, having spotted them, Laurier hacked the software and sent Sheed and Galina on a false match on the docks near the inauguration site.
Now alone, My'shell failed to capture Laurier as he was about to kill Okur, the rogue assassin stabbing her shoulder before he fled back to the docks where he subdued Sheed. As Galina and My'sheel engaged Laurier, Sheed used the diversion to recover his gun and took aim at the renegade. While Galina was ordering Sheed to kill Laurier, My'shell received a message from Erudito alerting the members of the collective that their HQ was attacked by the Templars. Hearing Sheed arguing with My'shell about his unwillingness to follow Erudito's protocol and hide, Laurier offered to help them in order to save Charlotte de la Cruz.
However, upon their arrival above the island, Laurier's jet was shot down by the Templars and Sheed died in the crash. Playing dead, My'shell was used as a bait so the Assassins could ambush the Templars sent to investigate the crash site. As Laurier and Voronina were bickering over their next move, M'shell convinced that the best course of action was to take down the Templar warship that shot down their plane and would prevent any future escape from the island. 
My'shell and the Assassins assaulted the frigate, killing the Templars who were onboard. However, during the fight, Laurier was badly burned by an explosion which destroyed the ship. After Laurier told them that he could not go further and that they had to left him to die, My'shell and Voronina left to rescue their friends. Back to their destroyed plane, the two women reunited with the survivors of the Templar assault only to discover that de la Cruz wasn't with them. At the same moment an Assassin rescue team sent by Gavin Banks, consisting of Arend Schut Cunningham and Kiyoshi Takakura, arrived in a helicopter and picked up the group. Later, they rescued Charlotte de la Cruz who was then cornered on another part of the island by Templars led by Ortega Sanchez, killing them all with the chopper's machine gun.
Joining the Brotherhood
By 2017, My'shell had joined the Brotherhood and was placed under the mentorship of Voronina. While she was training with her harsh mentor on the rooftops of London, Voronina received a call from de la Cruz asking for backup after her team had been butchered by an unknown party in Hong Kong.
