Dossier Edit Tali was born in aboard the Rayya. Having reached maturity, she departed the Migrant Fleet on her Pilgrimage. On her travels she began hearing reports of geth , who had never ventured beyond the Perseus Veil since driving her people into exile, and became curious.
She tracked a patrol of geth to an uncharted planet, waited until one was separated from its unit, then disabled it and removed its memory core. She recovered a file from its audio banks that revealed Saren Arterius was behind the attack on Eden Prime , but possessing the file put her in grave danger. She was pursued by Saren's forces, and escaped to the Citadel.
On her way, Tali was shot and had to go to the Med Clinic for treatment. Chloe Michel she wanted to trade her information to the Shadow Broker in exchange for a hiding place, but was double-crossed by Fist who was working for Saren. She was expecting to meet the Shadow Broker in person but met a "messenger" with a group of assassins. Tali threw a tech proximity mine to defend herself, and was aided by the timely arrival of Commander Shepard's team.
To repay the Commander for saving her life, Tali presents the proof that Ambassador Udina and Captain Anderson needed to get Saren's Spectre status revoked. Tali's data also provides the first mention of the ancient machine race called the Reapers , who hunted the Protheans to extinction, and the mysterious Conduit.
Wanting to help fight the geth and prove herself, Tali then joins Shepard's team. Tali spends her time in the Normandy's engine room. Engineer Adams is very impressed by her knowledge, wishing his crew were half as smart as Tali. They often work together to disassemble any abandoned technology, such as old orbital probes that the Normandy's survey missions discover. Shepard can chat to Tali about her fascination with starship technology and the Normandy's unique design, especially the enormous drive core.
Tali talks about life as a quarian nomad, her Pilgrimage and the ramshackle three-hundred-year old vessels in the quarian Migrant Fleet. Her mother died five years ago due to an airborne virus and although Tali is sad about this loss, such deaths are an unfortunate fact of life aboard the Flotilla. She also reveals that her father is the head of the Admiralty Board—the highest authority of the quarian people—meaning everyone has high hopes for Tali's Pilgrimage. Tali also offers some insight into the geth: She explains that her people struck first to try and stop the geth before the war started, but underestimated how far the geth had developed.
Shepard can debate this with her, pointing out that the quarians basically attempted genocide against another sentient species. At first Tali is very excited about being on board the Alliance 's most advanced vessel, but she begins having problems. She can't sleep because she's not used to a ship that runs so quietly to a quarian, a quiet ship means a dead engine or worse, a malfunctioning air filter. She also says that compared to the crowded conditions of the Migrant Fleet, the Normandy feels disturbingly empty, "it's like half the crew is missing.
Tali enjoys visiting the crowded, noisy Wards on the Citadel because they feel like home, and she particularly likes the music in Flux , hoping to take a copy back to the Flotilla. If Shepard treats Tali with respect, she is very grateful, explaining that her people are usually treated like second-class citizens. On Virmire , at the salarian camp, Tali is nervous about the upcoming assault on the base, but promises she will "fight with fire" for Shepard's sake.
After the mutiny, when Shepard steals the Normandy and heads to Ilos , Tali enjoys the adventure of it all, but wonders what the Council would do if the Citadel Fleet caught up with them. Shepard is sure Tali's father would pull strings to keep his little girl out of jail, but Tali isn't convinced: She claims the quarians once tried to find Ilos as a new potential homeworld, but they never expected it to feel so unwelcome.
After speaking to Vigil , Tali is saddened by what happened to the Protheans —like her people, the Protheans tried to fight back against the machines, but eventually lost everything.
Personal assignment Edit If Shepard chooses to partake in an Alliance campaign to drive the geth away from the Armstrong Nebula , a cache of data may be found in a terminal at the main geth base on Solcrum , detailing the evolution of the geth since their split with the quarians.
Back aboard the Normandy, Tali asks for a copy of the data if she is spoken to. Though it is heavily encrypted and might take years to decipher, it is a perfect gift for her Pilgrimage. Shepard can agree to her request, or refuse—it is classified Alliance data, after all, and official appeals for access can be taken down the line. If Tali receives a copy of the data, she is very grateful as it will enable her to return to her people once the mission is over.
She reiterates her pledge to help stop Saren. If Shepard refuses, Tali isn't sanguine at the prospect of the Alliance actually releasing the files to the Migrant Fleet. She pouts at Shepard putting humanity's interests at the expense of the quarians, and she opts to leave the crew as soon as the mission is over—in order to find something of equal value and complete her Pilgrimage on her own.
