Do you think the belief in the Herald of Andraste will last?

The people who believed originally weren't exactly that bright, imo, so they will likely continue to believe

It would be hilarious if they started some sort of cult and intuited hidden messages from any Inky Declarations to be a code to them.

I think they'll at least be remembered for sealing the Veil Tear.

But much like how Ameridan was eventually remembered as a human warrior with potentially a mage lover, the much of the Inquisitor's true history will be erased.

Depends on which part of the continent we're talking about. Places more devout like Orlais and Antiva I can definitely see remembering them, while places like Tevinter never really bought into it so they'll be forgotten.

For this discussion, I assume we’re working under the assumption that life goes on past Solas and his plan?

If yes, then I think they’ll be remembered. Like Hanako said, it will probably vary by region. In the very short term; say ~9:60 Dragon or thereabouts, I’d expect nearly everyone South of Tevinter to remember and believe in them. Past that, though, it’d probably fragment a bit. Some will continue to be absolute in their faith that the Inquisitor was the Chosen of Andraste. Others will recall a pseudo-religious leader that saved everyone and others still will decide that they were just some soldier the advisors put out for parades and speeches.

I assumed that reason for that specific title was the vision that Drakon claimed for himself as is contained in the Canticle of Exaltations: Prophesy at the end of the Chant. This starts with the "Air rent asunder, spilling unearthly light from the waters of the Fade, opening a baleful eye to look upon the Realm of Opposition". This is a precursor to Andraste's return in order to render judgement on behalf of the Maker and bring in a new age of peace and eternal life for the world. It goes on to say: "And in that baleful eye I saw the Lady of Sorrows, armoured in Light."

The Chant of Light is recited in full week on week in every Chantry throughout Thedas, so even ordinary people who could not read would be familiar with this image. So there was a massive explosion, following which a great rent opens in the sky (that could be said to resemble an eye), showing the Fade beyond and, as the PC walks out from it, the soldiers were able to see a female figure behind them, shining with an unearthly light. It seems pretty clear to me how the PC acquired the title of Herald of Andraste.

Flemeth also alludes to this when she says they are a "Herald of a New Age". Naturally Flemeth is not showing belief herself in the meaning everyone else has given to the title but she could be being ironic because she is aware what she has been nudging events towards over time and Fen'Harel is likely to bring to fruition. So our PC may well be a herald of a new age because the world will be transformed if the Veil is destroyed but that would have nothing to do with the Maker or Andraste, unless you take the view that Solas is the "Maker" of this current world with the Veil and Andraste was connected in some way to Mythal. Which, knowing your feelings about everything being connected with the elves, I am sure you would reject.

Well, in Exaltations, Andraste returning does follow on the opening of the rift pretty closely, but then it doesn't make any mention of a Herald either. Since the Chantry initially opposed the idea of you being the Herald and I don't think ever officially endorsed the title (I may have missed something there if I am wrong), even if the new Divine did approve the Inquisition, it is easy to see how they can backtrack from the whole Herald thing without losing face. This is why I tend to think the whole Herald aspect of the Inquisition will be dropped and the PC will be remembered as the Lord Inquisitor of Thedas who sealed the Breach if they are remembered at all.

I don’t get what you mean about the Andraste stuff being disproven.

... and you seem to believe anything Chantry is always right, and we ought to discard other sources because of your mighty say-so.

I'm not gervaise, but I understand it to be implied. If the first Inquisitor was an elven mage, and we've met the man who created the veil, than what else has the faithful of the Maker intentionally and unintentionally gotten wrong? When you add Drakon into the mix, I would hold nearly everything that modern Thoedosians to believe about the Maker to be Drakon's political fabrication. Therefore all that is known about Andraste is specifically what Drakon wanted you to know.

I thought I just did. Actually Sera hit the hail on the head, I'll give her that. After the Temple of Mythal she insists it was just a ruin full of demons and that none of what they claimed was true because:

"There can't be a bunch of gods and the Maker. Doesn't matter how much or how little you believe, those don't fit. So call me stupid but I believe the stuff not made up by dead people who failed. Mythal is a ruin full of demons."

Now, due to her prejudices against anything elven, she chooses to believe the Chant of Light, even though technically Andraste was also a dead person who failed (in her quest to bring down Tevinter and free the slaves forever). However, this assertion is made before we actually meet Mythal in the form of Flemeth, before we discover Solas is really the Dread Wolf and that the current reality is the result of him shutting away the elven gods by creating the Veil. So if Sera couldn't reconcile the two things before all this, how much more mind blowing must it have been for her afterwards.

Now in world you can understand why, when the Inquisitor returns with this story after meeting with Solas, people are inclined not to believe them. Their reaction is probably pretty much like that of Sera. The apostate elf had clearly gone crazy, probably having been possessed by a demon. Thus, whilst he clearly needs putting down before he does any real damage, the idea that he actually created the Veil is just bullshit. Because you cannot reconcile Solas' story with the Chant of Light and whilst it is understandable that people in world would find it hard to accept the former without a massive crisis of faith, we can take a more objective view of the whole thing. The only way Solas' story fits with the Chant is if you accept the person who spoke with Andraste was not the creator god of the world before the elves existed but the creator of the world as it is currently. Then the sequence of Veil cutting off the Fade, followed by the rise of the humans fits the facts. Also, the Maker's claim to have imprisoned the gods. Even the idea of the Fade being the domain of the Maker, the Black City belonging to him and the Magisters breaking into the Black City and releasing the Blight on the world being condemned by him as bringing "doom upon the world" because the gates to the city had been sealed for the express purpose of keeping it within.

That is what I mean between the difference between them revealing whether there is an actual "Maker" as distinct from Andraste's Maker. Of course, I could be entirely wrong about the direction they are heading with all this but even without that, Solas having claimed to have created the Veil and having the power to alter reality as he did, which should really only the purview of the Creator of the Universe, did somewhat diminish their claim never to prove the Maker one way or another.

And you come off as utterly insane rejecting the Chant because it comes from those disgusting humans. And I ignore what you say because it lacks rationality. 

People would claim to be related to the Herald even if the relationship was outlandish. They would do that even if the Herald wasn't called "Herald" due to sealing the rifts. Claiming to be related to famous people isn't new.
