#House Hresvelg who started as a symbol of coexistence between humans and nabateans is terminated by its last member

Hybrid Nabatean headcanon?

Uh...

Well, if you insist

HC Nabateans are made of magic.

Sothis made them using “magic” since she is the reason why “magic” spread through the land (Fodlan+other countries), after her arrival in Fodlan.

Flayn is a special case - because she was born when Sothis was still alive. 

That is why she can transform, and have a different crest from her dad.

Sothis blessed her mom with a longer life than what patient 0 would get from a simple crest transfusion. That's why Cethleann is closer to a Nabatean than any other hybrid - Sothis lit gave her mom more “magic” to make her offspring close to a Nabatean.

Nabatean pregnancy takes more time than a normal human one (and is more dangerous if the mother is human, that’s why Sothis “strengthened” Cethleann’s mom even if she had Cichol’s crest). Flayn is thus closer to a Nabatean than other hybrids, she can transform, have her own crest and has the longer lifespan. She can even be cut for parts.

Roughly it is equal to more or less 10 years (Ena took around 20 years to give birth to her son?). This is partly why it was more or less codified that Nabateans has to give their blood to their human partner, so the human could spend time with their offspring.

Post Sothis hybrids are different -

With the Progenitor God dead, there is less magic in the air, only the Nabatean can pour his magic, but they cannot gather it on Sothis’s levels, so the kid ends up as a strengthened version of a human, with a few Nabatean traits.

As a result, post-Sothis, Male Nabateans have a lot of difficulties to “create” a hybrid, because they cannot pour magic constantly to the baby who isn’t in their bodies. As a result, interbreeding with a male Nabatean rarely produces a viable offspring, and if it does, the baby is much more closer to a human than a baby born to a Nabatean Mother.

Ditto for second gen children, hybrid Mother can pass on more “magic” and Nabatean genes than a hybrid father.

Hybrid Nabateans would have a crest stone instead of a heart, but age faster than a pure blooded Nabatean and wouldn't be able to use as much magic as a Nabatean could. They share the same crest as their Nabatean parent, but their bones aren’t shiny and cannot be used to craft relics. However, they are still “super-human” as in, uh, being able, idk, to tank 1 nuke (instead of 5 like Rhea), jump 20 meters high and have a way more “magic” than a human, even a crested one.

They still have the traditional pointed ears, green eyes and green hair.

Second generation children (1/4th Nabatean) have varying hair color and eye color, but round ears. They only share a crest and have a very slightly longer lifespan, but not the additional Nabatean traits.

---

Hybrids were actually common before the first Agarthan War - but afterwards, they became ultra rare - some Nabateans thought humans were arrogant, greedy and full of hubris, so Cichol is the only odd loser who grew fond a human.

Of course, everyone loves Cethleann, so maybe humans aren’t bad and all.

But then Nemesis happens.

Noa's children were born after the Chalice - I mean, Noa's kid (rumour says she had a son, who had a lot of difficulties to get a child, so she got a daughter too, but then, both managed to get a child). She expressly wanted to avoid to have more than two kids, and told her kid(s) not to have large families too.

With time, of course, her decree was forgotten - at least the "why" - but House Nuvelle still tried to have the fewest heirs possible, and tried to hide/keep their crests pure, i.e. not intermarrying with other crested families. Actually, their obsession to become “purer” was to return to Noa’s first kid, who was able to do “inhuman” feats - they wanted to gain a closer concentration of Nabatean blood - but sadly it didn’t happen.

By the 4th generation, all Nabatean traits disappeared save for a pronounced affinity for magic.

Constance still has stomach-aches after eating a Zanado Fruit, but she doesn’t immediately throw up like “regular” humans. (The Noa fruit was engineered based on Zanado fruits, they are supposed to be Zanado fruits but tempered to be able to be eaten by humans because Noa wanted to share a Nabatean recipe with her grandchildren, who cannot eat Zanado Fruits, so she made the Zanado Fruits edible by humans!).

Willy the Loser might have tried to get a kid, but given how Seiros the Warrior kept on being a Warrior and always depleted her magic when she was fighting, none could be allocated for a kid who couldn’t “grow” post conception.

Seiros the Warrior never knew about this, naturally.

Wilhelm’s heirs, and House Hresvelg members, are thus 100% human.

When creating Citrus’n’co, Rhea thought about hybrids but thought creating an artificial body out of human and Nabatean materials wouldn’t be able to host Sothis’s powers and/or consciousness, so she only used her own, uh, fluids/materials to create her artificial beings.

Billy, born from an artificial Nabatean and a human, is able to host Sothis’s consciousness and powers, was a welcomed surprise. Granted, Billy might also have worked because they were born “naturally” and not “artificially”.

However, given how Citrus was not a “real” Nabatean, Billy has no hybrid powers nor abilities (but then they merge with Sothis).

Post Sothis fusion!Billy, should they have children with the Nabateans and Flayn, would create beings on Flayn’s levels, for all intent and purposes, a Nabatean.
