I think I'll write a fic where Saren did not die and was freed from indoctrination as sovereign died. You can always free a puppet by killing it's master. Now I hate to compare Saren to a puppet but indoctrination tends to do that to people. Shepard had severely wounding Saren in the side. Sovereign believed Saren was dead and attempted total control over him. It was not possible. Sovereign eventually shifted all it's attention to Saren allowing the fleets to destroy it. Saren left as the rubble fell on the citadel tower. After Saren was freed he went into hiding on omega feeling guilty and depressed. Eventually joined archangel A.K.A. (Garrus) and saved his team by shooting Sidonis before he could reveal their whereabouts. Garrus never knew his identity. Garrus ordered his team to abandon him once the merc groups discovered them. The team was dispersed when Garrus was recruited by shepard. Saren was later found on virmire by shepard. I won't use Amonis without your permission.
