Grissom Academy
The Alliance's Biotic School
The Jon Grissom Academy was a Systems Alliance space station and elite school for gifted human students, best known for the Ascension Project that trained young biotics. During the Reaper War it became the target of a Cerberus raid to capture its biotic students.
The Jon Grissom Academy was a Systems Alliance space station and elite school for gifted human students, commissioned in 2176 and named for the explorer Jon Grissom. Though publicly devoted to math, science, and the liberal arts, it quietly offered training to students with biotic ability through its Ascension Project, which sought to develop their talents and integrate them into society. During the Reaper War the Academy became the target of a Cerberus operation to seize its biotic students, prompting an Alliance rescue. (Mass Effect 3; Mass Effect: Ascension)
Mission and the Ascension Project#
The stated mission of the Jon Grissom Academy, commissioned in 2176, was to serve a student population demonstrating excellence and passion for math, science, and the liberal arts. Its entirely human student body ranged in age from the early teens to the mid-twenties. Though the fact was not heavily advertised, the institution also offered classes for students with biotic capability through its Ascension Project, a program devoted to training these young biotics and integrating them into normal society. The station measured 1.1 kilometers in length, weighed some 375,000 metric tons, and supported a population of 8,620. (Mass Effect 3; Mass Effect: Ascension)
Early history#
The Academy was named for the Alliance hero Jon Grissom, and after his death a memorial plaque was erected in his honor in the station's mess hall. The Ascension Project remained its most prominent program, helping biotic children reach their full potential. The station was not immune to danger: the Reaper-controlled Paul Grayson once boarded it seeking to learn more about the ongoing Ascension Project, disabling or killing much of the station's personnel before David Anderson, Kahlee Sanders and Kai Leng arrived and killed him. (Mass Effect: Ascension; Mass Effect: Retribution)
The Cerberus raid#
During the Reaper invasion of 2186, war closed most schools, but fewer than twenty teachers and students stayed on at Grissom Academy to train biotics and prototype technology for the Alliance. The Academy then came under attack by Cerberus forces intent on capturing the students. The assault went unnoticed at first because Cerberus broadcast a turian military signal claiming that the station was being evacuated by turian ships, a ruse that echoed the false turian report the Illusive Man had once used to send Commander Shepard into the Collector ship trap. (Mass Effect 2; Mass Effect 3)
If the Commander chose to intervene, the pilot Jeff "Joker" Moreau used the Normandy SR-2 to distract the Cerberus cruiser and its fighters while Shepard's team boarded the station. There Shepard found Kahlee Sanders barricaded in a security room and went on to rescue the Academy's remaining students before evacuating them and abandoning the station, which along with nearby Elysium later fell to the Reapers. If Shepard decided against going, the Cerberus kidnapping succeeded and the captured students were subverted into working for the organization. (Mass Effect 3)

Commander Shepard
Commander Shepard was a Systems Alliance N7 marine who became the first human Spectre, exposed the rogue agent Saren Arterius, and led the galaxy's resistance against the Reapers.

David Anderson
David Anderson was a decorated Systems Alliance officer, the first captain of the Normandy, and a mentor to Commander Shepard. When the Reapers invaded Earth, he stayed behind to lead its resistance, and he stood at Shepard's side in the final hours of the war.

Jeff "Joker" Moreau
Jeff "Joker" Moreau was the Flight Lieutenant and helmsman of both the SSV Normandy and the Normandy SR-2, a brilliant pilot whose brittle bones never kept him from the cockpit. He flew Commander Shepard through every campaign of the Reaper War and formed a close bond with the ship's artificial intelligence.

Kahlee Sanders
Kahlee Sanders was a human Systems Alliance officer counted among its finest computer specialists and a recognized authority on synthetic intelligence. The daughter of Admiral Jon Grissom, she was drawn repeatedly into events surrounding rogue AI research, Cerberus, and the Reaper threat, and she devoted much of her life to the children of the Ascension Project.

Normandy SR-2
The Normandy SR-2 was an advanced stealth frigate built as the successor to the original Normandy and served as Commander Shepard's base of operations against the Collectors and, later, the Reapers. Built by Cerberus and later turned over to the Systems Alliance, she became one of the most storied warships of her era.

Systems Alliance
The Systems Alliance was the supranational government of Earth and its colonies, acting as humanity's military, exploratory, and economic arm in Citadel space. Within decades of its founding it won humanity a Council seat and led the galaxy's defense during the Reaper War.
