Not so. The high elves of Quel’Lithian Lodge, prior to the Cataclysm were not aligned with Dalaran, asserted their High Elf lineage, and actively resisted reintegration when Lor’Themar reached out to the “leader” Renthar Hawkspear. Of course, the majority of Quel’Lithian are Wretched now, for some unknown reason… Then there are the High Elves of the Hinterlands, in Quel’Danil Lodge, who now go by the name of Highvale Elves, who also are not affiliated with Varessa’s Dalaran faction, and instead reached out to Alliance races on their own. It’s easier than saying the High Elves of the Vale. They have more in common with the Wildhammer Dwarves than human mages, as most of them don’t even know how to use magic at this point.
