With this episode we had the reveal, though I think it was already suspected by people observant of the icons, that the fallen/abberant/(whatever the other one is) are variants of Jormag's power using the corrupted spirits of the wild.
Yet, Braham in a heated debate managed to seemingly free them from the corruption and use their power?
It was also inferred at one point that the spirits are some infinite spring of power?
But we still haven't learned exactly where the spirits came from, nor entirely what they're capable of.
We haven't had anymore details on the true connection between Kodan and Norn.
We haven't seen any Jotun or abandoned Jotun civilizations. We have this bow capable of damaging Jormag because of an ancient Jotun scroll commented on during one of Braham's conversations with the spirits, but why?
I hope we get to explore some of this moving forward and it isn't just centered around Braham with a quick transition to some Charr civil war. I know a lot of people were wanting us to explore this region to learn more about some of the more mysterious parts of the lore, but so far it doesn't seem like we're going to be getting too much detail about any of that.
