Plot twist!
I sorta figured something was going on but not exactly that. (SPOILER)Primarch a fal'Cie? Took me by surprised, I just figured the Sanctum Gov't was corrupted and the fal'Cie were trying to fix it, not summon their Maker.
I just (SPOILER)beat Cid Raines. I think I am near the end of Chapter 10...or I hope so!
