Links to pages not about otherkin per se, but that might be considered adjacent to us or thematically related.

Faeids: Your Gateway to the Fae - "Faeids are those selected by the Fae living in the Otherworld (Middle Earth, Tir Na nOg, Faerieland, etc.) to help prepare for 'the Great Awakening'. These are Humans, Faeries, or Faerie/Human Breeds (changelings) or those communicated with by Faeries for the purpose of bridging the gap that has developed between humans and Faeries long ago."
Elvin H.O.M.E. (Holy Order of Mother Earth) - the home page of Lothlorien Nature Sanctuary, the descendant of the Elf Lore Family. They host a festival called Elf Fest every spring.
Come Home to the Faerie Queen: One Mystic's Manifesto - "I've waited lifetimes for the Fey-spark in humans to fully ignite again. And, more and more, the ancient starlit blood has come forward. Finally, momentum hit critical mass; the magic's suddenly - and thoroughly - awake in huge numbers of people. Fey-touched! Star-drenched!"
Galactic Council Species Primer - some random connections to elves and Tuatha De Danann.
Ilsalunte Valion ("The Ship of the Valar") - "What unites us here is that we are all touched by a peculiar quality found in Tolkien's writings; and we think that this is because of the nature of Tolkien's experience in Faerie. In his own words: it is clear that the Fairy Gold that he brought back from his travels did not turn to withered leaves. It still has the subtle, magic flavour of that country. You could say that Ilsaluntë Valion is a place where we want to study this and who knows, maybe retrace Tolkien's steps into that realm - as far as is given to us. And if we should, to also bring back whatever we find there."
Alt+H - Alterhuman is a term coined (ca. 2016?) to attempt to encompass otherkin, therians, vampires, fiction-kin, multiples, soulbonders, other-hearted, other-linkers, transhumanists, postfurries, and basically anyone who is some kind of non-ordinary human being. "We strive to fairly represent people who identify as something other than human, or with an alternative human experience; and to help them fairly represent themselves. We want to bring to light the specific issues that alterhuman people face and begin to carve out spaces in society where they can get help with these things."
