The Commander has a lot of titles, and a lot of different names. Hero, monster, killer of the Council, savior of the Citadel, first human Specter. One name is definite between all; Shepherd.
Equestria is a peaceful world, one yet to even reach space travel. Yet, even a galaxy away, they are still affected by the defeat of Sovereign. They don’t know it, but they need not just a symbol, but a warrior.
Deep in the Void, the makers of the Reapers conspire to make an endless cycle of destruction within a universe to secure energy.
All shall be thrown into conflict together. Shepard will either lead a new flock, or let them be devoured by the wolves.
