this isn't what i THINK but what i would like to see (as i have no clue how the veil could tear so without it being a result of blood conflict weakening then breaking the veil)
and means looking an sandal's "prophecy"
One day the magic will come back blah, blah, blah, blah
unlike others i Don't believe this means everyone will become magical. But that the old magic that was lost over time will come back. this is important, because I don't believe the evil were immortal. Instead they had magic that pretty much made them immortal.
so when this magic returns the Elves become immortal once again.
as to the HE this requires an even greater stretch in logic.
who are the "gods" and the forgotten ones.
to me the god's are locked away in the golden city, at the centre of the fade.
the forgotten ones are the Old gods trapped not in an unknown void but locked inside the earth.
and it was one of the forgotten ones that lead the Imperium to try and take the golden city knowing the gods would kick them out, the moment they stepped foot their (which lead to the blight and the freeing of the old gods even if corrupted it was all Dumat's plan to destroy the earth as a way to get back at the dread wolf for his treachery.
But its not Fen'Heral thats coming back, Elgar'nan the chief deity of Dalish and god of vengeance. Remember despite creating life he is associated with blackness having thrown his father the sun (more on that later) beneath the earth.
it was he who turned the Golden city black to signify his vengeance idea (pissed off that the old gods/forgotten ones had broken the truce) it is his return!
think about it he was the creator of life (in dalish lore) but there was no man, man came later. Ever since man the dalish were pushed back further and further man reigning is an affront and its a return of the god of vengeance and in his rage escapes the golden/black city tears open the veil and returns to thedas to **** **** up.
which brings us back to the sun, as mentioned earlier the sun existed before Elgar'nan but was over thrown when he "burned" the life that Elgar'nan had created. but what if it wasn't a literal burning? what if the sun which was Elgar'nan's father after all created his own actors to slay the the elves?
that man was in fact created by the sun after all what imagery is the "maker" associated with? the sun.
so Elgar'nans return is all about vengeance, vengeance on the old gods, the blight, the darkspawn and the people who follow the sun and destroyed his people the elves…..humans. Elgar'nan threatens to destroy everything that he's opposed to everything that has damaged his creation.
Inquisition is not just about closing veil tears but stopping a rampaging god of vengeance.
those that follow andraste learn the maker isn't the be all and end all nor is the chantry "correct"
those that follow the old god's start to return step out of the shadows.
those that only believe in the stone learn there's more to life and digging holes.
those that follow the Qun are left questioning there every way of life.
and those that follow dalish teachings learn worshipping a god of vengeance isn't exactly the best thing to do.
this creates massive conflict over all especially for dalish inquisitors.
closing the veil and pushing back Elgar'nan may destroy old magic once again returning the elves to mere mortals to trod upon by others once again, but not doing so threatens to destroy the world itself.
but how do we defeat a god? well how about with the reincarnation of Urthemiel itself not a half dead blight affected old god, but a fully renewed "forgotten one" ready to go to to toe with the god of vengeance and return beauty to the lands once again. fittingly sacrificing itself in the process and leaving us all questioning just who is good and who is evil on the grandest stage of them all.
