Dark Energy AU: The Monster Within

5 years post DE AU: Best Left Said. Osco is gone. Spectre T'soni and Dr. Shepard are now scouring the galaxy for any traces of advanced exo-alien tech in order to preserve the safety of their home from similar such threats. But there is more than one universe out there; more than one T'soni, and more than one Shepard, as well. All just as determined, but not all heroes.
