Ok, so I'm not sure if any of us caught this the first time around, but did you notice during the E3 EA presentation there were several shots of what appear to be the main area where the massive veil tear is situated?
First off, look at this concept art? In the distance you can see the breach surrounded by black spiked rock formations:

Here's that same area from the presentation in-game, notice the same black spiked rock formations:

Close up of the area, again with the black spiked rock formations from the previous two (in the presentation it zooms out enough to see the breach directly above), however the area surrounding is changed which could be a result of the Fade gradually leaking into the real world, like what was happening at castle redcliffe in the demo:

Here's where it get's interesting, this looks to be the epicentre of where the blast hit. It's hard to tell from this pic but in the clip you can see the burnt bodies of the peace gathering victims (you can see bits of the old building behind them):

We've seen a close up picture of the one above before via Twitter when they asked us to caption it, notice those black spiked rock formations again:

And finally there's this picture. You'll notice that the Inquisitor/whoever is standing the archway facing those black spiked rock formations. However, the outer building seems to be intact so perhaps this is just before the blast where only a small veil tear was situated due to the weak veil, which then spread into a large one after the blast?... or maybe this particular picture was just staged for the presentation? Either way, this appears to be the area where the blast takes place:

There was no real point to this post, I just found it interesting and I hadn't noticed them before, lol.
