Ever since the First Contact War, the situation between the Systems Alliance and the Citadel Council has been tense. The aliens prejudices and laws against cybernetic intelligence target the Alliances Omnic populations very existence, and many see it as a miracle there already hasn't been a war started by the Batarians trouble making. As the galaxy balances on the edge of chaos, and an ancient evil awakens, the only hope for the future rests in the hand of the Alliances greatest heroes. The organisation that brought peace between human and Omnic, that stopped Talon, that discovered the ancient prothean ruins on Mars.
