So some things we were talking about yesterday, I happened to have amongst my screenshots.
First, how Solas says that he thinks it's the orb that opened the breach but that he's surprised Cory survived the explosion (i.e., perhaps he gave the orb to Cory to be activated and expected Cory to die in the process)
Second, I had asked where Solas said something about the elves and the old gods, because semantically it sounded just like the way DG phrased it (i.e., "the LORE doesn't tell us there's any connection"). Indeed, Solas says the same dodgey thing (from the same conversation), suggesting to me they are both twisting the truth. ("So what I told you was true... from a certain point of view."
)
Yeah, at this point, I agree with what Solas said first. The explosion was a rather fortunate accident for Corypheus, cause it certainly unleashed a crap ton of chaos by killing off a good chunk of the Chantry leadership, templars, and mages.
As to his surprise about Cory surviving, Solas, even as knowledgeable as he is, probably didn't know Cory could jump into tainted beings like that.
I almost read Solas' last words as being something to the effect of, "no surviving lore" connects the Old Gods to the elven people.
