Today in Anthem

If the Fade only serves as a tool for demons and 'evil bald guys' then it's as well explained as Anthem of Creation, I guess   Heck, in the first chapters of Anthem we've already had at least 3 people who have tried to achieve their goals via Anthem (including one supposedly evil bald guy, lol).

Also - should I remind you that the fact that the 'evil bald guy' wants to achieve his goals (never mind that that 'tool' is clearly something bigger than him so McGuffin it ain't) we have only learned about it 6 years after the concept was introduced?

All in all, the Fade is somewhat explained after multiple games, books and all the materials - yet we still find out how much we don't know about it, since not that long ago (story-wise) it was revealed that the Fade is in fact NOT really a separate dimension (whether you can walk in it or not) and was a part of the world that was separated from it by what turns out to be artificial, magical barrier (that most people have thought is permanent and primordial).

Again - it's something that came up only recently. Yet was set-up years ago.

...You realize that you use Anthem an its principles to power Javelins and fly, and in fact do most of the things in the game? This is pretty well explained and even underlined in the story.

That makes no sense. That's like saying that what we interact with, what affects the story and what the characters are all about in DA isn't the Fade but magical wands, runes and spells, while ignoring that they were all created in order to shape the Fade/magic and would make no sense in a world where it doesn't exist. You must be aware just how weird this argument is. The technology left on Mirrus is the kind of technology that wouldn't function if not for the Anthem and has been created specifically to harness and shape Anthem.
Does your back hurt from bending over backwards a bit too much? This argument makes no sense whatsoever. You're quite obviously trying to make Anthem what you say it isn't, but it totally is - something that serves a function in the story, by which I mean, powers virtually everything and moves the world/story forward, in fact in higher percent than Fade and eezo do.

In fact it almost seems like you argue that Anthem is just a matter of those ancient machines still being active somewhat, rather than a palpable force in the world?

But we already know very well that Anthem exists. It's not just ancient machines based on unknown tech - without Anthem the current tech people use wouldn't function as well and there would definitely not be people like Cyphers and the world wouldn't look like it does, nor function like it does. Virtually everything in that world is built around Anthem.
