Worn Out Welcome

I think everyone may be reading too much into that Meredith reveal. The series is set almost immediately after Trespasser. Even if they don't commission a second series, it can still be assumed that Meredith was dealt with off screen. Or they intercept and destroy the Circullum, so she is still stuck in a lump of red lyrium in Kirkwall.

I recall Varric telling us they were still stuck with the statue in the Gallows because it was impossible to remove it (or something like that).

Absolution has to also fit a timeline that has Knight Errant in it and the Dread Wolf Take You, both of which mention the statue in the Gallows. Varric was Viscount in Knight Errant and is still a major contact in Kirkwall for the Ben'Hassrath in Tevinter Nights, so at worst Meredith must have upped and left the city with her army, heading for Tevinter.

I don't see it myself but at most she will be a sub-quest along the way. It does really seem rather superfluous to have both Meredith and the Antaam both trying to destroy Tevinter. The Antaam have been given a much higher profile at the end of Trespasser and in associated media, so they are far more likely the ones we have to deal with.

Remember in Solas' picture she is shown with the sword, which she no longer has, and Cory is shown with the orb, which he also no longer has, so his mural is a bit odd if it is meant to be foreshadowing future encounters.    Varric also talks of friends losing life and limb as the camera rolls over those pictures, so the implication is definitely they are portraying past events.

Of course, the Devs could have been messing with us and giving misleading information in that trailer but for the present I am going to give them the benefit of the doubt.
