Is Solas going to succeed?

With regard to Sandal's prophesy that may well have been the direction they were taking initially with DAI, as shown by the 2013 trailer narrated by Morrigan, which seemed to fit with it (certainly with regard to the sky opening wide). However, whether they still intend to go with that plotline is anyone's guess.

Only half the original story for DAI has been told so it is possible Solas will succeed eventually. There are other hints that something big is going to happen. Flemeth definitely seemed to be predicting something back in DA2. The Inquisitor was regarded as the "Herald of Change" by both Flemeth and OGB Kieran. I don't believe their actions with regard to mages count since there are so many different outcomes and much depends on who ultimately gets made Divine. Morrigan is also seen as the inheritor of Mythal's power (by Flemeth and OGB Kieran), so I don't think we have seen the last of her either.

So whatever happens it is likely that things will not turn out as Solas intends them to. I think the next game will mostly be spent trying to locate and stop him against the background of the war in the north. At the end something will likely occur in connection with Solas which will then be the plot hook into the next game. I'm hoping we get a showdown eventually with either the two remaining Old Gods or with the released pantheon of Evanuris. If there is a resurgence of magic then the Titans are bound to get involved because it will likely awaken them fully.

It seems they're going for a synthesis ending for DA but with more set-up. So yes.

This is what it feels like to me.

I'm kind of cringing because I think a setting where everyone has magic is boring and the fact that not everyone in Thedas is capable of magic is something that endears me to the setting and sets it apart. But if they've had this in mind all along, I'm sure they're going somewhere with it...

Of course, Solas could be a red herring.

It's difficult to come up with a rational motive for lying there. Anyway, Solas hasn't told too many actual lies. He concealed lots of stuff, but that's not the same thing.

Hope he succeeds

Hm, what would that be like? Mortals trying to live their own lives, trying to ignore the call of the gods. But then a spirit of love or justice or faith compels them to fight its battles, warring with people who are seized by a competing spirit. Spirits that encourage them to act even against their own self-interests or loved ones. To risk their lives, to shun their own children, to act cruelly toward others. All in service to the idea that the spirit embodies, whether it’s moral outrage or fear or national pride.

Good thing spirits are fictional. I can’t imagine what it would be like to live in a world where people acted at the whims of massive shared ideologies. It sounds exhausting!

I dunno, but what if SALOS succeeds!?!?

Hope he succeeds and then the evanuris escape and chop him into small pieces.

It wouldn't surprise me if it turned out that something dire would eventually happen if you were to keep the veil aswell as if you were to rip it down. Like if you kept it then slowly the magic would dwindle further and further till everyone in Thedas was tranquil until the magic faded enough that the world could no longer suustain life or something - but if you let solas rip it down then current life on thedas will be destroyed in the raw chaos but the magic would allow other life to return.

Resulting in the protagonist having to go for some third option (provided perhaps by Mythal or some other powerful being) that would cause the veil to distintigrate slowly over decades/centuries letting the magic back gradually. So the current denizens of thedas would live without changing the setting too dramatically.

But that's just one of the possibilities I can think of.

I wonder if there can be a 3rd option where there could be stable veil breaches/ portals where spirits can come and go freely while the rest of Thedas remain in tact? Kinda similar to The Avatar type scenario?

However, my greatest concern is not whether or not Solas succeeds, but if something worse arises due to his plans. Much like how Corypheus ended up being the bigger threat, so that the Mage-Templar war was put on the side; I fear that Solas plans will be put on the side due to one of the Evanuris (Falon'Din/Dirthamen?) being released.

if Solas succeed, then that means Thedosians are beyond usless and stupid, cause there isn't as a stupid, simplistic and bland guy like egghead.
