Tents are not permanent homes mate, Buildings are. Tents don’t give warmth, shelter or protection. There are no buildings in Telogrus Rift because blizzard never put any because void elves were last minute decision. And they are only 20 of them. Without the Alliance High elves and Silvermoon exiles, they will eventually cease to exist. Can’t make a race with only 20 people. which is one problem with void elves. Void elves have not existed long, they don’t have 10000 years backing them up, which is another problem with void elves because they are still blood elves, their culture, traditions and language etc is still Thalassian. For them to be unique and different race, they have to start from the ground-up. And they can only do that by working together with the Alliance High elves and Silvermoon exiles. Build houses, towers and walls. (Why do they need walls you say? Because they are deep inside Void lords territory, that’s why. The void lords may not know the void elves are there yet, but they will eventually). And the void elves don’t fully control Telogrus Rift, there are still hostile void creatures in Telogrus Rift. They are even being watch by another Ethereal, Shadreen the Ethereal Watcher.
They might learn some Ethereal culture, traditions and language from Locus-walker and some void lord language in time. But that’s the thing. It will take time but they are not going become their own race by sitting on their hands in a tent. I know you said that there is no weather so there is no need for buildings, well who says there is even oxygen there? Its in space after all.
And blizzard could always change the outlook of Telogrus Rift that there might a bigger rock island that can be used as a city for void elves. Sure it just be a fort like Allerian stronghold at first, but in time it can grow and eventually become a city. But as I said nothing will happen if they just sit on their hands.

And if the artists at blizzard are given the chance to come up with ideas, they can make void elf buildings that look little different from blood elves, Night elves, Nightborne etc but is still looking elvish. I mean have you looked at the buildings at Azuna at the broken island? those buildings look different from the other elves that are playable but they still look elvish.
The Draenei that lived on Exodar and Xenedar, when the two ships were in space. They had very little resources to grow plants. What they did, is that they used the light to make plants grow. So too can the void elves use the void to give the Telogrus Rift life. By using the void. We have seen on Argus that animals there have survived and been altered by the void. The panthera for example can go into void form just like the void elves. So by using the void they can create something new, we have seen Umbric and his followers in Zul’dazar bring something dead to Life. (Im sure that’s how they made their voidstrider mount). There are alot of dead trees in Telogrus Rift, so if they used the void on those trees. Maybe they come to life.
I know some people say the void can’t heal. But shadow/disc priests have a skill known as Shadow mend and it does heal but also take a small amount of you. The Void is powerful but also punishable. But maybe as they learn more about the void and with Locus-walker’s help, They might overcome that drawback.
I hope we get to see more of Alleria and her void elves with Vereesa and Silver Covenant in the next expansion working together and also Im curious what’s going to happen with Sylvanas, looking forward for the next story questline.
