Ordinary Day

Hee! Well, the OOC answer to this, from what we know of the books, is that human/elf joinings do get occasionally tried. In Hidden Years, in the story about Tyleet raising a human cub, Aroree tells the tribe she was once 'curious' with the kept humans of Blue Mountain, and so she volunteers to be the one to try to teach 'Little Patch' about joining. But in the story, it goes badly; Tyleet, who is narrating the action, describes how 'our bloodsong is pitched higher than they can bear'. The young human is depicted fleeing the tribe in anguish, and this is the event that drives him to seek out the local humans and try to live among them.

We also know from the Shards storyline that Grohmul Djun lay once with Winnowill in her human form, and he later rails at her that he nearly "lost his soul" as a result. BUT, we know furthermore that in the Futurequest era, Jink, the (apparently) last surviving she-elf on Abode, takes human lovers--if they're telepaths. Because telepathic humans are apparently the only ones who can handle joining with her.

The favored theory among the Staff is that for most humans, joining with elves--who are active telepaths--is too emotionally intense for them to bear it. I'm playing with the idea of Arnos and Wayfound getting away with it because a) Wayfound is not a strong sender, and b) Arnos could be one of the first humans on Abode with early telepathic potential in his DNA. ;) Which isn't entirely bogus. There's a story in Blood of Ten Chiefs, that's even pre-Cutter-era, in which a human manages a very rough kind of sending by ingesting the proper kind of weird plant. So the potential had to start cropping up in human DNA at some point, even if it doesn't come into full bloom until the Futurequest era. :)
