'When He rises, everyone will see' — Sandal
It is already claimed in the teaser trailer that the Dread Wolf will rise. Solas, the next antagonist will rise up against his opposers in the next installment.
However, the Dread Wolf rising doesn't have to be him doing so physically, but rather, rising up to take responsibility in ending our Veil-like world to restore his elvhen People.
'I will save the elvhen people, even if this world may die' — Solas
Particularly, what will Solas 'rise up' to do when ending our world? The mural we saw looks as if the Dread Wolf is rising much higher above the elvhen bald-figure, and poses as a threat with its red eyes. Could Solas be looking for a source of power to rise against the Veil?
'The shadows will part, and the skies will open wide.' — Sandal
'I would've entered the Fade using the mark you now bear, then I would have torn down the Veil. As this world burned in the raw-chaos, I would've restored the world of my time, the world of the elves. ' — Solas
At the beginning of the Inquisition, Solas kept at a nearby village to retrieve the Orb that carried power over a period of time for millennia. Solas' plan was to retrieve the Orb after Corypheus had died unlocking it, and then have the mark which the Inquisitor bears.
His plan the whole time for this world, was to destroy it and revive the world of his time with the elvhen and also the evil Evanuris. He gave the orb to Corypheus so it could gain enough power to tear down the Veil, which is what he wanted all along. He would have risen up to power and created a plan to destroy the Evanuris before they got their chances of gaining ultimate power.
I believe not only his first personal plan involves him rising up to power against the Pantheon. But that he also 'rose' from a slumber he took. Solas now has awoken to a Tranquil-like world, and will begin his journey to go against the forces of this world. Seeking help where he can reach with spirits and the elvhen, and then opening the Veil in the sky and render the Fade into the Waking world as one.
'I was too weak to unlock it after my slumber' — Solas
He seemed quite sad when the orb broke after all the orb was key to opening eluvians and the Fade.
After defeating Corypheus, Solas’s last chance after the Orb broke was to reach out to Mythal and gain enough power to tear down the Veil. He takes the remnants she bestows to him, and he begins his journey to rise up against the Veil. He starts by taking over control of the eluvians, unleashing spirits to fight against the Qunari threat.
Solas isn't messing around this time, he finally has some amount of power to break the Veil and restore a world before it becomes bad. But how will he rise?
Thedas knows very little of the Dread Wolf, known as a treacherous, merciless, figure that is heavily feared in Dalish tales, the Evanuris fear it too.
'The pages of this book-memory?- warn of a terrible danger, a wolf with slavering black jaws and pits for eyes. The Evanuris-the elven gods-stand in a ring around it, as if preventing it from attacking.
"Beware the forms of Fen'Harel The Dread Wolf comes in humble guises, a wanderer who knows much of the People and their spirits. He will offer advice that seems fair, but turns slowly to poison. Remember the price of treason, and keep in your heart the mercy of your gods."'
— Note: The Treachery of the Wolf
This depiction of Solas having pits for eyes, and slavering black jaws, they warn those of the terrible danger coming. Wherever the Evanrus are hiding, they are surrounding this Dread Wolf to prevent any attacks. What could be speculated is the factor that Solas and the Dread Wolf could be different aspects of each other, like Corypheus puts an aspect in his Red Lyrium Dragon. This, could be closer to a red lyrium wolf.
What if, as described in the codex, Solas is going to finally reach the place were the Evanuris are hiding, use this aspect of himself, the Dread Wolf, to rip open the Veil?
However, the Veil is to be known recently to be weaker than it has ever been since the Breach:
The Tevinters once theorised that the Veil is thin in places that have seen great bloodshed. — Codex entry: Tears in the Veil
Demons seize every opportunity, every tear in the Veil, to enter our world. The Breach is living proof of the chaos it can unleash. In Hushed Whispers was living proof of how the world can become...
But it is theorized that the Veil tends to be weaker in places that feature, or have experienced, extensive death or use of magic.
‘Small tears occur naturally when magic weakens the Veil or when Spirits cluster at an area that has seen many deaths’ — Solas
The tear occurs because spirits are attracted to death and they press against the Veil. The Veil is particularly thin at night, when most people sleep and spirits are most active. The use of blood magic can allow the Veil to be torn so that demons may physically pass through it into the waking world.
Once the Veil is torn in places, it is extremely difficult to mend, and some might even say impossible. "Mending" these Tears, i.e. strengthening the Veil, is extremely difficult. Depending on the level of damage done to the Veil, it can be closed through several methods ei. The Anchor.
One place that is particular known to have the Veil thinner, is Kirkwall. A lot of chaos was constantly influenced upon that city, and that is ultimately where we first located Red Lyrium as well…
It is well known that the Veil is thin in Kirkwall, small wonder given the suffering in the city. But we've discovered the magisters were deliberately thinning it even further. Beneath the city, demons can contact even normal men. Did they seek the Black City to compound the madness of their previous efforts? Or was it something else? We've found a chamber where the Veil is at its thinnest, long-since looted, but the power is still there. — Band of Three, The Enigma of Kirkwall
What is known is that places around Thedas where deaths/chaos have occurred more than frequently, are now further weakening the Veil. For Solas, that only means an easy key to breaking the barrier that separates the Fade from the Waking World.
“You’d murder countless people?” — The Inquisitor
‘Wouldn’t you to save your own?’ — Solas
The sky may have never healed ever since the Inquisitor sealed the breech, which may prove worthy for Solas’s plan to destroy the veil. His execution to tearing down the Veil might work once and for all.
And the sky is healed. Healthy, whole, there’s just that left to remember.. - Cole.
A new dawn is appearing, the dawn is coming upon Thedas.
‘One day the magic will come back - all of it. Everyone will be just like they were.’ — Sandal
Solas will rise as the Dread wolf to take the Veil down, and whether his plans are fully executed, could be the end of our time…
‘We aren’t even people to you?’ — Inquisitor
‘Not at first, you showed me I was wrong, you were people and you deserved better. Like all the rest I used after one hopeless battle after another.’ — Solas
