In the name of Earth and Balaho, till the bitter end!

The Reapers say they do not know fear and never experience it, but how long will this remain the truth when Humanities greatest heroes from another dimension come here with ships and allies? Will the name demon rise once more, with now entire armada's of Reapers fleeing at the mere sight of him, or will humanity and their allies die fighting like the Protheans before them?
