Cerberus

Cerberus is a human-survivalist paramilitary group led by the enigmatic Illusive Man. Cerberus' core belief is that humans deserve a greater role in the galactic community, and that the Systems Alliance is too hamstrung by law and public opinion to stand up effectively to the Citadel races. Any methods of advancing humanity's ascension are justified, including illegal or dangerous experimentation, terrorist activities, sabotage and assassination. Cerberus operatives accept that these methods are brutal, but believe history will vindicate them. Nevertheless, both the Systems Alliance and the Citadel Council have declared Cerberus to be a terrorist organization and will prosecute identified Cerberus agents accordingly.
