Having learnt of the Ascension Project, a training programme at Jon Grissom Academy producing young human biotics with incredible abilities, the Illusive Man ordered for Cerberus operatives to infiltrate and secure the facility. Under their subdue-or-suppress methodology, the majority of Grissom Academy's security and staff were eliminated while defending the students. The only team preventing Cerberus from taking over the Academy is Kahlee Sanders: a director of the Ascension Project and one of the Alliance’s top technicians, and David Anderson: a decorated N7 marine and renowned war hero.
