Yep, like I said, that encounter in the Fade was the Inquisitor driving the bus. It makes it sound like we should be able to find him in the Fade. Could come in handy someday. 
Maybe this has already been discussed, but you know how Solas mentions the Herald riding in on a griffon? In the Emerald Graves, there's an astrarium that talks about Equinor, thought to be a griffon but also a halla. You see reliefs of elves riding halla into battle. Then there's this...

Those are wings on that halla. Hmm...
The astrarium codex also mentions that the constellation might have originally been of Ghilla'nain but the meaning supplanted because horses were sacred to the Neromenians, the progenitors of the Tevinters. It makes me wonder if the ancient elves and ancient Tevinter shared a progenitor race, which would put Kieran's words about "why do your people choose to look like that" in a different light. We know the old gods and elven gods are connected somehow so this has been bubbling in my brain for a while.
