Like I said earlier, people refer to their boats with female pronouns. This could be that. Or it could be as you said that even souls have gender. Or Titans choose theirs and Azeroth chose to be female. We really don’t have enough information.
It’s weird that Voren’thal hasn’t returned to Quel’Thalas, if I’m honest. I’m fairly certain Outland is secured, especially now that the threat of the Burning Legion has been ended. There doesn’t seem to be much of a reason for him and the Scryers to remain in Outland anymore, or at least, to not have returned to the banner of the Sin’dorei. By which I mean, I could see the Scryers maintaining Blood Elven outposts in Outland, and ensuring a steady stream of supplies or samples of unique or rare resources were being sent back home to be analyzed, studied, and experimented with.
Kind of always thought it odd that the Blood Elves never took more interest in Apexis Crystals.
As far as Outland’s High Elves, seems they’re sticking with Alleria as far as we can tell. The last we saw of Outland’s High Elves was Auric as a representative for the High Elven Pilgrims at the Sunwell in Wrath, and he nearly got arrested on made-up charges the moment Quel’Delar refuses Lor’themar. He wasn’t even there anymore when Alleria visited, and we also had an Alliance Island Expedition team named after him.
I don’t know what story Blizzard wants to tell where Quel’Thalas is concerned now that the factions are hugging it out. Given the mix of customizations between Void Elves and Blood Elves, they may as well just combine the races and make Thalassian Elves a neutral race at this point. Never made sense that Lor’themar exiled Umbric and his followers anyways. Just keep them off Quel’Danas and you’re golden. Granted nothing about the Void Elf, ‘Lore,’ makes any sense to begin with, but I’m getting way off topic.
I agree we’re overdue for some kind of in-depth update where Outland is concerned, and I would hope Voren’thal and the Scryers have pledged their loyalty to Lor’themar and their fellow Blood Elves again, regardless of maintaining a presence in Outland, or finally going home to Quel’Thalas.
