Well the High Elves (and later Blood Elves too) sent an expedition to Kalimdor (Winterspring) to find an artifact of power among the Highborne ruins there a lot of years before the First War, so they were still exploring the world physically and not just scrying magically from their capital.
Also I think another expedition of them found Northrend, an if the Dragon Isles had not been hidden, they would have found them too considering their proximity to Quel’thalas (actually even if they were hidden, they should have found them anyway perceiving the big amount of arcane magic coming from there anyway, especially from the Azure Span, the ancestral home of the Blue Dragonflight, and from Thaldraszus and their city Valdrakken…
We would need a new name for this Highborne elven faction though, and possibly a new name for the union of both Kingdoms into a single one if it happened, and a new name for a possible new Highborne race that is a mix of Blood Elves and Nightborne…lot of new names would be needed if we go solo but I would like it too…
After more reading, it seems the common belief (not the canon belief) on MMO, is that it was the Shen’dralar who were actually Azshara’s best. Built the Empire, scryed on all part of the Empire and the broken world there-after.
Again - I’m not sure if this is canon as I’m not familiar with any of that. I normally just go off what the Shen’dralar Ancient says.
(She doesn’t make reference to this, by the way - which is why I’m skeptical about it.)
Just call us “New Highborne.”
Nightborne do their varying arcane things. (Astromancy, Telemancy, Protection Magic.)
Blood Elves do their very specific arcane things (Blood Magic, Pheonix Magic, Fel Magic.)
Then we have the Nighthunters and Farstriders, with Halduron Brightwing and Nighthuntress Syrenne.
Then the Blood Knights and Duskwatch Guard, with Liadrin and Victoire.
Did they ban Erevien from the other forums again???
And no doubt Alleria is powerful, but someone should say to that poster on MMO-champ who almost RPs as her that she did run away from the Sin’dorei leaders and Thalyssra when Rommath wanted to arrest her in the Sunwell, but Lor’themar allowed her to leave as an exile, otherwise if she’s so powerful she could have killed them all and teleport away (since he says she can teleport anywhere…)
That poster defends Void Elves more than I defended Blood Elves 10 years ago when I was a teen… and that’s all it needs to be said about it…
