"Right, it makes sense that Laerdya wants Gwyn to get the benefits of the ritual, but" he says, looking downward, arms folded in thought, "Gwyn isn't an outsider who has done a service for an elf community. It's not like there's a test or something, but she just hasn't done something that would make her a ruathar. I don't know if that's an antecedent for the ritual or if it's just something anyone can do for anyone on a whim; I would think not, but still, I don't know."
"As for the ritual itself, I don't know specifics, but I know... stories? I've always thought it was a myth. I've heard that the translation of 'star-friend' is at least a little bit literal; the ritual is supposed to happen at night under the stars. Then, the ruathar would be given a gift, usually something magic, and would be taught the magical phrase that would show they're a ruathar. Anybody can say the phrase, and saying it doesn't just magically make you one, but only the ruathar can use the magic which makes it legitimate. Apparently, the listener can tell the difference, but I'm not sure how? Again, this... just sounds like a story you tell to kids. Anyway."
"After the ritual, the ruathar would be led to a dark place to sleep and rest - I'm serious, here, not making this up as a prank - which would ideally be someplace with an open, empty tomb prepared, like a cemetery or a burial ground of some kind." He looks at her. "I know. I know. Anyway, they would spend the day locked in darkness, sleeping or meditating, and then when they rose again the next night, they were 'reborn' to the people who had adopted them. Reborn under the stars, reborn a ruathar."
He pauses, considering a moment longer. "Yeah, I think that's all I know. It's... I mean, the stories say it's a sacred ritual and that being a ruathar means you're a true friend to elves, so I shouldn't be so glib about it. The Nailo elders would be furious with me for being so disrespectful. I've just - I've never seen it or anything like it in my many years living in and studying nature, so I'd always kind of written it off, you know?"
