I thought it went without saying that the Mark was bestowed before the explosion, since it was what help Quizzy alive
I always thought something similar to the fall from the bridge in HLtA happened: Quizzy instinctively opened a rift in the nick of time that s/he and the Divine passed through and were spared from the explosion because they were no longer present for it.
Only the last thing we see before explosion is Inky writhing in pain, Corypheus jumping right at them and Justinia still hanging in the air. We don't really know what happened in that split second, nor why or how they survived (and why only Justinia and Inky found themselves in the Fade but not Cory), or when exactly the bestowal if the Anchor happened. Unlike HLtA this isn't really a clear moment.
Plus, we have to take into consideration that the place itself is special, given that it was an ancient temple with great power and mysterious purpose - and it had heaps of purest lyrium beneath it that is directly responsible for making lyriumghost!Leliana that is pretty much identical to the original. Which is sort of similar thing that later happened to ghost!Justinia - is it her? Or does she identify with her so much that she effectively her? Was Justinia in the Fade right after explosion the ghost already or the real deal? ... What if similar thing happened to Inky? They actually didn't survive, but were given a new body and chance in one split second? It's a wild speculation at this point, I know, but still a distinct possibility. Especially that the writers went out of their way to mention a ghostlyrium!Leliana in a way that makes it a rather big deal. It doesn't appear to be something just introduced for the lulz.
Ah, I see, you were wondering why Solas wouldn't have used it before the veil, not after. My mistake. What I was mainly trying to say was that I find the introduction of time-magic rather inconsistent simply because I can't imagine people as powerful and learned as the Evanuris not using it, but there are no indications that they did.
Right, which is why I have my doubts that time can simply be erased in a way it was suggested. I mean, that would make the story and timeline one giant mess
It's already enough that we know that IF the world eventually merges with the Fade, it can be shaped by will and imagination...
Interesting gif! Hmm, I think this may not be intentional. In other words, I think the darker, crystalline forearm (that looks like a rift, interesting) we see is a separate model than Quizzy's actual forearm, which is made to glow in this scene. Presumably, since the camera angles are different in gameplay, you wouldn't see this inconsistency. It looks quite creepy though!
It's entirely possible that it's just an unintended effect in animation. Still, there are things in cinematics that are oftentimes not shown yet are still there - like Solas holding romanced Lavellan's hand when he kisses her. Not anything we can see in cinematic, but yet a detail that bears significance.
My interpretation of Quizzy closing her fist is that Solas has complete control of the Mark now, and there is no distinction between Quizzy's arm and the Mark anymore. So it mimics Solas' own movement (and it's also worth noting that Solas does indeed use his left hand).
Back to the crystalline comment: It seems like the Mark is slowly turning her body into the fade, or something like it. Perhaps this is why Solas could wield it fully, but not you, since the Elvhen were part of a world with no distinction between the fade and the material. Their bodies could handle it, or their bodies were already partly fade-y if you buy that they came from spirits. This also explains why Solas was surprised that any Inquisitor could handle (no pun intended) the Anchor. While he may have been right in the long run, people can live "without" a hand, so the Inquisitor would stay alive until it spread to something a corporeal being would need, like the heart.
Well it could also be that... well... the mark belonged to Solas. the "Fade" hand follwing his movement might simply be because of the connection between it and its proper owner. Cole also mentions that "Your hand hurts. A heartbeat. Not yours. Hammering the beat of a song in its final verse. I'm sorry."
Though I'm not sure what it means
Hmmm... what if the Anchor was acting up because Solas himself was growing in power, and since it's technically HIS mark, Inquisitor is in that way pretty much directly connected to him. Yet since the power is overflowing and Inky has no body or trained will to handle this, their own body reacts the way it does.
I don't know what it means for the future though. But I can't help sometimes to think that - with some hints in the game, the comparisons, the bestowal of his own, important fortress into Inky's hands AND the recent revelations from Patrick Weekes, who suggest to look for visual similarities between post-epilogue scene with Flemythal and scene of meeting SOlas in Trespasser - sometimes it almost seems as if Solas... is grooming a successor. Maybe not a literal successor perhaps, but maybe someone who will inherit his struggles. That's a distinct possibility too.
