This post contains MAJOR SPOILERS from late in the set. Do not read this post unless you've read ALL of the books that have been published. You've been warned.
Some fans have wondered if Gethen could be Sophie's father. Another theory is that Forkle is Gethen's father, which would mean that Gethen is Sophie's brother.
I read a post on the KotLC Wiki by Park.Song that posits that Gethen is Sophie's brother:
Gethen – A Theory
I personally doubt that Gethen is related to Sophie. If Forkle is the father of both Sophie and Gethen as Park.Song suggests, then Sophie's brother Gethen killed her father. I very much doubt that Shannon is taking this series down that dark of a path. Likewise, I do not believe that Keefe will kill Lady Gisela. Some plot developments are a bridge too far for this particular series.
However, Park.Song makes many good points and is right about certain details. I wholeheartedly believe that Forkle is Kenric and that one of the Forkle twins is Sophie’s father. There are too many clues for the series to be heading in any other direction. I have compiled them (see post) and have gotten a lot of flak from people who are deeply offended by that post. I enjoy theories, and I don't understand why what I've compiled is so upsetting. As best I can figure, it's because they have their hearts set on the series concluding in a way consistent with their personal head canons.
The beginning of the Kenric/Forkle reveal occurs in Kenric's Forgotten Secrets, when the reader learns that Kenric asked Prentice to be his Keeper (of the Black Swan) and that Kenric knew specific details about Project Moonlark (Sophie's mother's identity) that could only be known by Forkle himself. Yes, Kenric said that he heard about suldreen from hearing Oralie say it, but he stepped away from Oralie when he told her so that she wouldn't detect the lie.
I find the points about Gethen's name coming from Norwegian words to be interesting and certainly enough to give me pause. They might be false clues planted by Shannon. She has placed so many clues through the books that it’s reasonable to assume that some clues are red herrings.
Park.Song also mentions Forkle's use of Leto and Loki in their post. One Forkle identity is Leto, and that name is the same as the Greek goddess Leto, who is the mother of twins Apollo and Artemis. Forkle's middle name is Loki. The Norse god Loki has sons, Nari and Vali, who are sometimes described as twins. The twin thing is interesting, and the names could have been early series clues that Forkle would be later revealed as a pair of twins.
It's also possible, as Park.Song states, that the names imply that Forkle is the father of a pair of twins. Park.Song suggests that Gethen and Sophie are twins, but Sophie's embryo was frozen for years before it was implanted. I am skeptical that Gethen and Sophie are twins or even siblings. I do have another idea, however. Before I get to it, I want to talk about twins in KotLC.
Biana points out that all the decisions they keep questioning were probably decided by Fallon (Nightfall, page 451). The decisions include the bias against multiple births, the match system, and the ban against Pyrokinesis. Fallon himself says that "things from our past are often more than they seem" (Flashback, page 33). I suspect that the real reason for the bias against twins is because twin elves are stronger, not weaker.
Linh tells Tam that "we're stronger together" (Legacy, page 730). Linh and Tam are said to have very strong abilities.
Two of the Dizznee triplets have manifested. While elves are said have unruly abilities soon after they manifest, I wonder if the Dizznee triplets' abilities will prove to be very strong.
And then there are the two Forkles. Oralie said that Kenric was one of the very best Washers. If Kenric is Forkle, then that would be another pair of twins with strong abilities.
I wonder Tinker and Elysian could be twins, since they both have red hair. Elysian is an ancient with long ears. Tinker keeps her hair piled on her head, which could hide long ears. They could even be identical twins, since identical twins can have different eye colors. Elysian has turquoise eyes, and Tinker has gray-blue eyes. Both Elysian and Tinker have freckles.
Tinker is an unusually gifted Technopath. Elysian has the ability to take away other elves' abilities. If Tinker and Elysian are twins, then that could be the original source of the bias against twins. Fallon might have lied about twins being weaker because he was fearful of how strong they were.
Now, let's continue with my idea about twins. I previously suggested (see post) that Eleanor Olivia Wright could be a backup moonlark to Sophie. If Eleanor is part of Project Moonlark, then she must be Sophie's half sibling at minimum. Eleanor's full name rearranges as the anagram "love Oralie with a grin." Maybe it's just coincidence, but it's strange enough to make me wonder. It could even be a red herring planted by Shannon.
Regardless, I firmly believe that Kenric (one of the twin Forkles) is Sophie's father. Most fans shut down this idea, because Forkle told Sophie that Sophie's parents don't know each other (see post refuting Forkle's statement). If Forkle was truthful, then Kenric isn't Sophie's father. That is a given. The problem is that Forkle could have been deceptive, and I don't understand why most fans assume that Forkle must have told the literal truth.
If Forkle is Kenric, then he could not admit that Kenric is indeed her father. Sophie would quickly draw some uncomfortable conclusions. She'd think about Kenric's death, which is truly just a disappearance that is an assumed death. Sophie would also wonder how Kenric came to know about Project Moonlark. She'd think about how Kenric was a Telepath, and Forkle is a Telepath as well. If Forkle is Kenric, then he had to lie to Sophie to keep Sophie from figuring everything out.
In the post about Gethen, Park.Song said that Forkle reacted defensively when Gethen suggested that Sophie's embryo was frozen. I agree that Forkle's reaction was odd. In fact, I feel like Sophie's embryo must have been frozen, and it's mighty interesting that Forkle was so touchy about it.
Were there two frozen Moonlark embryos? Was Eleanor one of them? I've struggled with this idea, since I haven't been able to figure out who would have carried Eleanor's embryo.
It's now occurred to me that both embryos could have been implanted in Emma Foster, and that would make Sophie and Eleanor a pair of twins. Emma is overweight, and baby bumps can be less noticeable in overweight people. It would have been possible for Emma to be pregnant with twins and not know it. While uncommon, some fertility doctors also deliver the babies. If Mr. Forkle, while posing as the fertility doctor, took care of Mrs. Foster throughout the pregnancy and delivered the babies, then information about how many babies Mrs. Foster carried could have been kept from her.
Is it possible that twin elves are stronger because their abilities are strengthened by the other as they develop in the womb in close proximity?
Here's something else. How would the twins have decided who would be Sophie's father? What if each of them was the father to one of the girls? Currently, this feels right to me. Each twin wanted to have a child with Oralie, and so each of them did.
Of course, all of this is ethically questionable. Even what we know for sure about Sophie's creation is questionable.
This is all just wild speculation on my part, but it's interesting to think about. Even if I'm completely wrong, Ethan and Eleanor Wright must be of great importance. We do know that Eleanor is hiding from Lady Gisela and the Neverseen. We just don't know why.
.............................................................
July 21, 2026: I wrote everything above the divider months ago. I would now phrase some of it differently, but I'm leaving it as is. I want to add my current thinking.
I remain staunch in my belief that Forkle is Kenric, which means that Kenric was a pair of twins, one of whom is now deceased. Forkle tells Sophie about how he and his twin studied genetics, trying to figure out why twins were considered weaker (Nightfall, page 179). The twins realized that DNA could be adjusted to impact abilities and that was when they decided to join the Black Swan.
I read something more into this passage. I believe part of the reason the twins reached out to the Black Swan was because they wanted to prove that twins are not weaker. For that reason, I firmly believe that the twins created two Moonlarks. I believe both Sophie and Eleanor are the Moonlarks. Now wait... keep reading to the end before you shoot this down. If you're thinking what I think you are, then I will address it as part of my theory. Stay with me. You also might want to read this past post, The Clues about Ethan and Eleanor.
I struggled for a long time trying to decide which Forkle twin would have been chosen as Sophie's father. I settled on the second-born twin, thinking that the second-born twin would have been considered by other elves as weaker. The Forkles' thinking would have been to prove that the second-born twin was not weaker by having him be the father of the Moonlark.
I then realized that wasn't it. Of all the injustices in the elvin world, the bias against twins is the one that impacted the Forkles more than anything else. They wanted to prove it wrong. They needed for the Moonlark to have a twin to disprove the bias.
I believe that Eleanor is the other Moonlark, and that she is Sophie's twin sister. One Forkle is Sophie's father, and the other Forkle is Eleanor's father. Since the twin Forkles were actually twin Kenrics and in love with Oralie, both of them would want to have a child with Oralie. Even though it's ethically problematic like everything about Project Moonlark, this feels right to me. I feel like this is it.
I believe Ethan Benedict Wright II is the fifth Forkle identity, and Dr. Wright was likely the name used for the Fosters' fertility doctor. That's why Ethan Benedict Wright II's obituary leaves off his title of doctor. That the omission of doctor was specifically mentioned by Keefe in Unraveled means that its absence is significant.
Why has Eleanor Olivia Wright been hidden away? She's probably Talentless. Oof. The Forkles' big plan went awry. A Talentless Moonlark twin wouldn't help prove that twins aren't weak, so Eleanor had to be hidden away.
Now, your objections:
"Eleanor can't be an elf because she would have already manifested." I just addressed the lack of manifestation of an ability. If Eleanor is Talentless, then she won't manifest.
"But Eleanor is human!" We're told that Eleanor is human. Eleanor says that she's human, but Sophie thought she was human until she met Fitz. We don't know if Eleanor is human.
"But Eleanor's eyes are green! She can't be an elf." And Sophie's eyes are brown, but she is an elf. If Eleanor is another moonlark, then her eye color being wrong supports the theory.
I believe that Lady Gisela has tracked down Eleanor and likely has her held captive. I expect Eleanor to reappear shortly into the upcoming next volume, #10 Elysian. Keefe might touch hands with Eleanor at some point, causing her to manifest a latent ability. I also have a theory about what will happen next. I have a lot more I could write about this, but I will stop here.
