Dragon Age has an 'uber-plot,' which BioWare seems to still be following. It all builds up to 'the last thing you could do in the world that would break' it.

Tool up, gang. We're mounting an daring raid in order to find and secure the Dragon Age mega-plot document. This thing is real, and it details the meta-narrative of the entire series, culminating in a kind of explosive conclusion that would make any further games in the series unplayable.

How do I know? David Gaider, former BioWare developer and Dragon Age lore author, told Eurogamer there is such a thing. It's existed since before Dragon Age Origins. Gaider said, "There was a plan when we created the world."

His approach to worldbuilding consisted of "seeding plots in different parts of the world, that could be used in a game or a single-game," but also to layer in "the uber-plot which I didn't have a certainty that we would get to, but I had a good understanding of how everything worked together."

Dragon Age was more than just a single video game. Future writers would have to take Gaider’s uber-plot in to consideration when creating future entries in the Dragon Age series. The problem was that most of it existed only in Gaider's head.

"I'd mentioned it, I'd hinted, but never really explained how it all related." When BioWare made Inquisition, the writers became impatient with his memory, or lack thereof. They pinned him down and dragged out the uber-plot, before committing it to "a master lore document, the secret lore that we had to keep hidden from most of our team."

Even though I'm not a big Dragon Age fan, I would (hypothetically speaking) commit at least moderate crime to get my hands onto that thing. Access to it was restricted to senior writers.

Gaider hasn't worked at BioWare in over a decade, so it's fair to ask if the writers are still following the uber-plot. Gaider has been surprised to see that his concepts in The Veilguard have "more or a little" held up during his absence.

This at least suggests Gaider's original vision for the end to Dragon Age is still there. It could even be the plot for a future game. (Or The Veilguard for all I know, since I haven't beaten it.) Gaider says, "I've always had a dream of how it would end." He doesn't reveal what this looks like because "we could still get there." He does say that it all comes down to "the last thing you could do in the world that would break" it, though.

I understand what you are saying, Mr Gaider. Prepare yourself for Dragon Age 5 - This time there are Reapers.
