Well, Nozdormu's vision confirms a few things:
- Deathwing's current cannon humanoid form seems to be similar to his Cataclysm artwork/ingame model that was never used. Probably without the metal jaw.
- Galakrond's size; we now have a rough size in comparison to proto-drakes. Previously we only had the artwork of him on the mountain with the 5 Aspects close to the "camera" so it was hard to gauge. Now we have drakes in his mouth so it's easier to figure out.
- Nozdormu says he "was Aspect of the Bronze Flight". They lost majority of their powers when empowered the Dragon Soul, but the other 3 Aspects (Alex, Kalec, and Ysera) have been referred to as Aspects since (correct me if I'm wrong on this). Does Nozdormu not consider himself one as he lost his powers, or is it for another reason that we don't know yet?
- The ceremony of Empowering the Aspect seemed.. simple. They got in a circle, Alex was lifted into the sky, surrounded by light and evolved. Previously, we've been told (through Dawn of the Aspects, though) that the ceremony involved the Titans acting through 4 Watchers to empower them, but there are no Titan-forged in the area. Was the ceremony simplified on purpose or retconned?
