I have a work-in-progress description of Queen Nualia available on my website, which you can read here. It importantly notes some important details about her voice and mannerisms, and also how her sexuality relates to her character. If one is interested, they can read the Dark Elf lore for a more in-depth view into the sexual physiology of dark elves, as well as their culture and how it reflects Nualia's character.

In a nutshell, though, Queen Nualia is a sexy, huge-tittied elf who loves getting fucked, and effectively sees men as toys whose sole purpose is to pleasure her.

She is a young woman in her late 20s to early 30s  (in relative human terms), soft-spoken yet confident in her words. She is a noble by birth, and her voice reflects that. Please read the description linked above for a more in-depth detail of her voice, and samples of what kind of speech I am looking for.
