The Third of the Dextro

AU. No more reapers/collectors. After ME1. Shepard attempts to take back Rannoch, with the help of a huge army, and unintentionally stumbles across a new race of alien, and a dextro at that. Will this new race be friendly, aggressive, advanced, or primitive? Read to find out! Rated T for now, might change later if it gets too bloody/wordy.
