Making Sense out of the Senseless (Spoilers)

The boss you'd just finished killing was supposed to be a tiny fraction of its power, right?

If so, I think why you can't kill the damn thing is fairly obvious.

Well, that and it's the size of a fricking mountain.

King Alistair:

Haven is in the Frostbacks and they sit on the border between Ferelden and Orlais. As you yourself noted, Marquis Durellion - an Orlesian - owns the land.

New Divine Election: Vivienne was a prominent member of the Orlesian Court and Circle of Magi. Thus, she has as much a claim as Cassandra or Leliana.

You think so? It's a survival mechanism, solidly grounded in evolution, and we fear more than we'd need to because false-positives may give us a (figurative) heart attack but won't kill us, but false-negatives certainly will. So we are the offspring of those who feared more rather than less - and survived as a consequence. As usual, evolved mechanisms can be co-opted by other important aspects of our lives, and so there are now even more immaterial things we can come to fear, triggered by ancient imprints or cultural phenomena. Fear may appear complex because it pervades our existence, and because it's ancient, not every instance can be easily explained so far, but at the bottom it's a simple phenomenon.

You may think that this is all theoretical, but this knowledge has actually helped me overcome fear in the past. There is no "Great Old One" analogue here, and understanding brings power.

TO answer a few of them:

Red Lyrium: According to Varric, the Gallows was sealed off to prevent the spread of red lyrium into the rest of Kirkwall. If Sebastian stayed with you to teh end in DA2, there is a War Mission where he sends aid to Kirkwall and the Inquisition can help clear out the red stuff

The Orb: It's entirely possible the Orb could have created another Anchor, but would likely take a prohibitive amount of time. Cory said you interfered with a ritual "years in the making"

Solas fully intended Cory to die in the explosion caused by unlocking the ORb, then saunter over and claim it himself. He did not realize at the time that Cory had mastered Body Surfing.

Solas also knew the whole time what artifact caused the Breach and that it wasn't destroyed. HE was using you (and the Inquisition) from the very start.

Demands of teh Qun: Gameplay and Story segregation. THere are, presumably a lot more Vints out there than we are shown. More than the Charger or even the Inquisitor in all his/her awesomeness can handle.

Viddasala: Face it, very little about Qunari armor makes sense

The Anchor: Well, the Inquisitor is "perfectly fine" except for the minor detail of MISSING AN ARM!!!

The faction you go after is apparently greatly weakened by your actions. The leader of said faction is likely at best out of favor with Cory and at worst dead.

Vivienne: She's a candidate because she's part of your Inner Circle and connected to the Chantry you do have to take specific actions to make it happen, though. THere is no War TAble mission to support Leliana, however, just agreeing to support her nets you as much support as actually doing the mission for the other two.

SOlas and his staves: Maybe Solas has an inventory too, and just didn't tell you? He seems to do that a lot

In all likelihood, Corypheus kills the lieutenant who failed him.

There are also a few Venatori in the Red Templar army marching on Haven if you watched that cutscene carefully.
