Maker this, Chantry that, Andraste's knickers, Blah Blah. Seriously kind of fed up with the overly religious dialog everywhere especially since every game exposes more of the truth that none of it is real. Also that Qun is another giant collective mind **** that needs to be toned down.
"very game exposes more of the truth that none of it is real" - What? No. From DAO to DAI there is nothing to prove that the Maker is real but there is also nothing to prove that it is not. It is pretty much like real world, when you create a myth of an almighty being the rules over the whole creation, possibly multiple dimensions, you can't prove of disprove existence. Something can only be proven true or false when it exists within time/space, within the universe that the beings analyzing it live in. Entities like God and the Maker supposedly exist outside the creation thus it is not even precise to say that they exist because they do not have a proper representation within the boundaries of time and space and are not made of anything, instead all things exist in them, they do not exist within constraints, they just can't be defined at all, even if they existed it wouldn't exactly be classified by "existence" because it would mean they are, somehow, limited.
So the better scenario when talking about God or the Maker is proving whether some claims about them are true or false. I can't prove god does not exist but I can prove miracles don't exist, well, specific miracles of course, happening within our timeframe at least.
Back to the Dragon Age series, we have found VERY little about Maker/Andraste. Nothing prove them true or false. Personally I have a feeling the Andraste was Flemeth and Shartan was Solas. Then the whole Chantry would be a lie, well, not for everybody, but at least your post would make sense... but with what we know now, even with all extra game lore, there is nothing "fake" with the chantry.
