#it's time for the Tolkien fandom to rise yet again haha

[arofili]

i haven't read the silmarillion or anything related but i was wondering how do elves's fëas work?? like i read somewhere about them sharing this fëa bond with people they marry so their fëas meet and that's what makes the marriage marriage in the first place. but im not really sure about that, don't people's fëas normally touch even if they're not married? and what happens if they do touch? this is weirdly specific but im just curious,,,you don't have to answer if you don't want to ofc! thank you if you do answer my curiosities haha and you still don't, ty too! (i asked you this bc i feel like you have a lot of knowledge about elfs)

Hey anon! So, a lot of what you're talking about is fanon, though it does have basis in canon. From "Laws and Customs among the Eldar" we learn about fëar and hröar and elvish (largely Noldorin, to be specific) marriage customs.

It's worth noting, though, that LaCE underwent many revisions and is a highly dubious document as it was written in-universe by Aelfwine, a mortal from the 9th century CE who found the Straight Road to Valinor. That concept in and of itself is a framing device for Tolkien's "translation" of the Red Book into English, and isn't one he kept consistent throughout his writing or one he was ever fully satisfied with - it never made it into the texts published within his lifetime, and doesn't make an appearance in the published Silm, either. And as I said in a previous meta dealing with LaCE:

Maybe this is something Tolkien changed his mind on between writing LaCE and writing this section of what became the published Silm. Or maybe this is an in-universe distinction: the in-universe writer of LaCE is unclear but implied to be a human, not an elf, possibly Aelfwine; the writer of the Silm as we see it is Christopher Tolkien’s edits of JRRT’s translation of Bilbo’s translation of Noldorin loremasters, the chief of whom was Pengolodh. It’s complicated.

That being said:

LaCE doesn't actually offer that much information on the nature of elvish fëar in relation to marriage. We do get the quote that "It was the act of bodily union that achieved the marriage, and after which the indissoluble bond was complete." Since human concepts of marriage are mostly legal/social engagements, and by no means indissoluble, this strongly implies something different is going on with elven fëar when they marry, but it's not stated outright. Still, the wording of "bond" in relation to "marriage" gives rise to the fan-embellished concept of a "marriage bond" that is very popular in fic/meta about elf marriages.

This concept is further supported by the description that a "greater share and strength of their being, in mind and body" is required for elves to create children (when compared to Men). It implies a closeness between a married couple where their "minds" (aka fëar) are as involved in the child-making process as their bodies. Later it is specified that after marriage, elves remain individual people with individual "gifts of mind and body that differ" - a strange thing to emphasize if there was not the possibility for misconstruing married elves as becoming literally one being.

For elves, marriage is forever: the Valar state that "marriage resides ultimately in the will of the fëa." Yet later in the same paragraph, it is explained that elves who are re-embodied need to be married again, because marriage is also of the body and the first body had perished. Confusing!

There are more notes about fëar in this essay, and the concept is mentioned in other places as well, but that's the basic gist of the concept AFAIK. (I highly recommend perusing LaCE yourself if you're interested in this topic! And remember that this is fandom, you can accept or discard certain aspects of the document as you see fit. I know I do.)

Most of your questions deal in extrapolation from canon - I would argue there's a strong basis for the concept of a marriage bond in LaCE, but it's not explicitly spelled out. I can't give you firm answers, but here are my personal headcanons about fëar and bonds. Everything that follows is headcanon, unless I explicitly state otherwise.

Elves are born with bonds with their parents; these bonds are important for the health and happiness of a growing child. (There's another line in LaCE about how the parting of parents and children in their youth is "a grievous thing," which is my starting place for this particular headcanon.) I also think that they have bonds with their siblings, though this is less supported; I just think that living with and sharing parents with someone is likely to foster the slower/less formal creation of a bond. Twins, however, are born with strong bonds between one another, having shared a womb.

(I also think certain Unbegotten elves - aka the first 144 elves who awoke at Cuiviénen - came into being with bonds, thus allowing for Unbegotten elves to have siblings, like Elwë, Olwë, and Elmo. But you could also argue that, depending on how you deal with timelines, those three brothers are not Unbegotten and were born the "normal" way.)

Then there are chosen bonds. These are the kind we hear discussed (albeit vaguely) in LaCE. Marriage bonds specifically are formed when elves "unite in body" and invoke the name of Eru. My personal (aroace) take on this is that sex makes the process of bonding much easier and faster, the naming of Eru and the intent to bond is what's really important, so if a couple would rather not have sex they can still bond. And it also opens up room for debate on which specific sexual acts count when it comes to bonding, what would happen if Eru's name wasn't invoked, etc.

But I also think bonds can be created in contexts other than marriage - found family, for example. I've seen this most discussed in the context of Kidnap Dads, but it could apply in many scenarios: you decide you want X person to be part of your family, and that means you want to bond with them. In the case of orphaned children, if you go with the idea that they need a parent-child bond in order to develop properly, this could provide substitute/adoptive parents to fill that role. Or it could be that you feel like a certain person is your sibling, but you weren't born of the same parents, but you still want them to officially be your family, so you form a sibling-bond with them. These are bonds that occur without the ~physical union~, and therefore take more time and effort, and thus are less common - but they do happen.

All these bonds are basically the same in terms of function: they make ósanwë (mind-to-mind/telepathic communication) much easier and more natural, they connect two fëar together in an indissoluble way, they show a depth of commitment and love between the bonded eldar. But they are valued differently in society, and created/brought into being in different circumstances.

As for fëar "touching" - that is, in my opinion, poetic license for communication/closeness through such a bond. If you touch your spouse's fëa, for example, that's connecting with them to see how they're feeling, possibly passing along comfort or a message, etc. This "touching" is basically ósanwë, I guess? Which, in my headcanon, you can do if you're not bonded to someone, it just takes more effort and closer proximity if you don't have a bond in place.

Hope this helps, anon! Feel free to send in another ask if you have more questions!
