It would be so cool if we could have those. I would quite like to meet her. What was her name again? I can’t remember.

There was a link that led to her Twitter, but I think that has disappeared.

This page http://outofsightgames.com/a-heros-call/audio-demos/ has contact info for some of the A Hero's Call voice actors. Maybe you can try to contact her from the information provided there.

Nate Wales, if you ever have need of his voice in Luna Stories, is also very receptive to the blind community, he posted on the forums for a while, and he also made Intro's for Liam's live streams.

Sorry

Actually, if I recall correctly the link given for Ariane Vai went to a Facebook page dealing with a series of books, so I don't think that can be used to get in touch with her. As for Nate I think he'd make a good host for a You Don't Know Jack style game since he pulls off snark quite well.
