Haven't read Elegy, but all the excerpts I have seen on read really make it seem dire AF for the Night Elves, it makes them sound like they were freaking decimated.
Which makes sense given that through all the conflicts since Vanilla, Teldrassil was the only true safe civilian center for NE, the constant conflicts with the horde perhaps making the tree very populous. All the other relatively major civilian centres in nothern Kalimdor, specially Lor'danel and Astraanar, were just razed, and if there's any settlements left out there, they are most likely military outposts.
So NE civilization was truly dealt a almost fatal blow, It's not that they lost a large part of their people, is that they lost the last standing cultural center of their people, the heart of their new place in the world after the Third War. Most of what is left on Kalimdor of the NE are military outposts, in terms of cities, towns, cultural centers, they have almost nothing left.
Val'sharah and Hyjal remain, but at best as enclaves, at worst as neutral lands that now exist on their own, neither of which represent the day to day of Kadorei culture.
So does the alliance no have a third kind of homeless elf? Will this newfound symmetry lead to a new development?
