Gender and sexuality

Earth's myths and stories have always featured transgressive characters, those who defy the moral certainties of the mundane world, and allow us to think about boundaries and why they might or might not be a good thing. Few are more transgressive than the Norse trickster god Loki, who not only transformed into a woman (or female animal) on occasion but also sometimes dressed in women's clothing just because he felt like it.
The fae, too, have a much looser attitude to gender and sexuality than most mortals. There are some species of fae that seem to be all-male or all-female, while others are androgynous or able to shift between sexes as will. For all these reasons, same-sex relationships are considered just as valid as opposite-sex ones. The only sexual practices considered off-limits are those involving non-consent, including minors and non-sentient beings.

Gender roles

Among the fae there is little or no difference in the status of the sexes - they are equally magically powerful, and their long lives mean that they seldom need to reproduce, so females spend only a tiny fraction of their time raising children. And since most humans in Andlang were raised there, they have embraced the same equality of status.

Humans

While humans are predominantly heterosexual, the attitudes of the fae have made it impossible to impose Earth's hidebound moral codes on the humans of Andlang, who thus enjoy far more equality than their Earthly counterparts. If anything, the humans of Andlang are rather more likely to be queer than on Earth, since there was far less incentive for them to go home once taken captive.
