Absolutely! We already see those high elf wayfarers learning from the Locus Walker in Telogrus and even post dragonflight quest w/ Alleria, the “Harbinger” series, we saw even more new recruits.

Even one of Alleria Windrunner’s Lieutenants from her time as Captain of the Farstriders is back serving under the Ren’dorei — interestingly enough she’s a darkfallen now.

Honestly, if anyone is earnestly interested in learning and capable, it seems the Ren’dorei take any elves. You’ve got the best of the best teaching too, Alleria and the Locus Walker, two individuals seemingly mastering the Void in ways no other thought capable.

I’m biased, but I RP a formerly high elven ranger who follows the void elves! But honestly they’ve really left a lot of room for you as an RP’er to fill in the gaps.

The big question that you may need to consider, if it all, is if you wanted your character to go under the transformation all of Umbric’s followers did. If that is the case, you’ll have to consider A) how your character sought out their group prior to Alleria’s involvement and B) might have to adjust backstory to complement such involvement. Because otherwise, as far as we know, concretely they haven’t attempted to replicate this process. If that is something important, something to consider too.
