So, a bit ago I did some digging around and saw some quests I hadn't seen anyone talking about.
I've done some more digging around and found: one, two, three
Looks like my prediction re: the Vale's future that I made in the above-linked thread is correct. I mean, those spell tooltips are still pretty vague, but, c'mon ... between that quest text and these tooltips, it's pretty obvious what's happening.
