I know this isn’t real, there were no Half Elves among the group of Blood Elves who were turned into Void Elves… at least we’ve no information about this happening.
However, I was wondering whether this would be acceptable or ‘valid’ from a roleplaying perspective? To create a Void Elf and roleplay as a Half Elf who was interested in learning more about the Void, and joined this group of Blood Elves and consequently got caught in Nether-Prince Durzaan’s transformation ritual…
Not even something that you have to worry about. Its already canon. I would link, but the forums are being mean. Look up ‘High Elf Wayfarer’. They are High Elf NPCs you can see in Telogrus Rift. And it would not be too much of a stretch to say that there was one there during the original fiasco that turned the first batch of elves into Ren’dorei.
EDIT: When I originally posted I thought you had said High Elves… I still don’t think a half elf would have more issues being in a situation than they would in any other situation.
There doesn’t seem to be anything about the ritual itself that relied on specific species. I would like to point out however that the Ren’dorei are already a minority group so…keep that in mind if you’re the type that’d be concerned with being too special.
It would be a VERY big stretch given that Half-Elves are pretty damm rare and there’s only one canon example in game.
My bad. I had misread the title and never went back to edit my post. I had originally assumed that the OP was asking about High Elves. Which are very easily done.
Still, if the OP was going to make a half-elf, outside of the normal rarity of a half-elf existing, there is nothing stopping them from being a Void Elf. Unless you have a roster of every elf that was in Telogrus Rift, it is possible that one was a half-elf. Especially since these were all outcasts from Silvermoon so the normal Blood Elf elitism would not have as much sway. Its not like this group was hand-picked to go to the void.
Up until the moment they went Void, they were pretty much your typical Blood Elves.
You know I don’t bother arguing with you. So stop trying. All of your ‘facts’ are heresay and opinions.
That’s a broad assumption with zero proof. It’s not unlike Blizzard to make halflings out of many species. See Garona Halforcen and her child Med’an who is half human, quarter orc, quarter draenei.
So if I parse the logic of your argument, just because we have one Me’dan, there’s a whole nation of them out there somewhere?
If that’s how you read it then you read it very incorrectly. The question was not, “Should void half elves be a playable race?” In fact, it was quite far from that. I trust that if you have the capability to write this quiet erroneous path of logic of yours, then you have the capability to reread the original question and understand it.
I’m RPing an undead half-Elf who bound himself to the Void, which essentially turned him into a half-Ren’dorei. I don’t see any reason other half-Elves might not have done the same. Just because we don’t know of any canonically doesn’t mean it’s off limits for roleplay, far as I’m concerned.
Technically it’s the ONLY batch of Void Elves that exists in canon. But we have no idea just how large a “batch” that was. or how far that experiment reached. But numerically they are arguably the smallest population of canon races.
Thank you, Malvalen 
And thank you too guys! Your comments have been helpful
Any time! I always support and encourage more half-Elf (and other half-breed) RP. 
You can’t really because Med’an is not only not in game but practically retconned into non existence
We both know that WoW lore extends beyond what you and I see in game. There are cinematics, books, comics, etc. Whatever they decide is canon, really. You say Med’an is nearly retconned…um proof? Alex Afrasiabi confirmed on twitter that Med’an is very much canon, but that he’s not a Guardian.
Also can’t…what exactly? Can’t mix races that Blizzard hasn’t mixed yet? That’s an incredibly racist thing to say. Nevermind though. There are half elves in the game. And I’m sure at least ONE of them would be able to control the void like Alleria has.
This isn’t a question of established, proven fact. It’s a question of possibility. Also this is fantasy…nearly anything is possible through magic, even Blizzard themselves have used that line. You keep saying this and that can’t happen because it hasn’t happened in game, but you’re forgetting that the lore and canon of Azeroth is so much more than just the game.
And lore is exactly what argues against it.
The only half-elves we’ve seen are not in Quel’thelas, in fact the only ONE we’ve seen was Arator who was trapped on Outland with Khadgar’s original expedition. Half-Elves are despised among in Quel’thelas so the idea that any of them would have been part of Dar’khan’s group given how much he despised Humans would be extremely improbable. Lore itself argues against them being present.
One, irrelevant info you speak. Two, there is nothing preventing the RP of the being.
The possibility of such a person is remote yes but not absolutely impossible thus allowable. Let it go. Stop bringing this solved and asked question back up.
Dar’khan? What does he have to do with this? Void Elves aren’t followers of Dar’khan or anything like that - they just used his findings regarding the Void, nothing else.
Plus, we’re talking about the Blood Elves who were already exiled from Quel’Thalas and were living in the Ghostlands - I don’t think it’s far-fetched to see a Half Elf doing business in the Ghostlands, meeting these Void Elves by accident and deciding to join them and help with their study.
The Void Elves’s research was based Dar’khan’s discovery of the Telegorous Rift and an artifact that he left behind that was later used by Magister Umbric. in the near fatal ritual that caused the creation of the Void Elves.
