Both the Shen'dralar Highborne (the trainers of the new night elf magi) and the void elves (the ren'dorei) are fairly prominent elven groups in the Alliance - or at least the void elves are, the Shen'dralar were interesting when they first rejoined the kaldorei, but nowadays, seem to be much less prominent.
They both share certain similarities:
1. They are both of Highborne heritage
2. They are both seekers and keepers of forbidden knowledge, and are reasonably adept at the arcane arts.
3. Both their peoples have secluded and isolated themselves for the most part for thousands of years.
4. Both were exiled from their original homes (Eldre'Thalas and Silvermoon) by the Horde, although understandably so.
5. Both were at least originally mistrusted and misunderstood by much of the Alliance.
I wonder if there is any interaction between them? For example, what would happen if Mordent Evenshade met Magister Umbric or Alleria Windrunner, for example?
Or in more general terms? Would it be possible if the two groups (with such low numbers after the Fourth War) tried to work together and cooperate, even if out of sheer pragmatic necessity, exchanging their knowledge and skills with one another? Would most of the Highborne view the void elves positively, and vice versa? And how would their quel'dorei (high elf) cousins view both of them, most likely?
