The Blanketfort (crying and throwing up) - The Official Solas Thread [Spoilers]

Not to reignite this heated discussion, but in terms of combating Solas, it's actually an inspired choice.

No-one would suspect that the (former) Inquisition would set up shop under the ruins of Haven. Anyone who might witness them being there would easily assume that they're visiting to pay respects or pilgrimage. The location is still a holy site and may contain a memorial to those who died at the Conclave and during the attack (from the optional war table mission). And as a the site of a major defeat, it'd be the last place you'd expect for the Inquisition (remnants) to want to return to and make their secret HQ.

The Breach also drove all Spirits from the vicinity of Haven and even after it was sealed, it's doubtful they'd want to return out of fear or from the severe damage to the Veil making it unpleasant to linger there. That makes Haven an effective blindspot to run counter-intelligence from, as Solas can't use any Spiritual observers to listen in and gather information. Of course, that wouldn't stop him from entering dreams, but that's why Dwarves could be very useful as they don't dream at all, blocking another avenue for him to listen in via.

(Although we have seen Dwarves capable of entering the Fade on rare occasions. Marathari was able to send Varric into the Fade and she wasn't even a Dreamer, so an experienced one like Solas may easily be able to force Dwarves into the Fade, negating this potential advantage entirely).

But to the topic of weird character models... yeah, whatever happened to age Teagan and Justinia so much in ten years?

(Going by TME, I'd guess that the answer is likely "dealing with Orlesians". Maker knows dealing with them on a regular basis would age anyone!)
