Are they at all weirded out by human biology? They probably aren't as weirded out by Yuu as Yuu is of them since they're all more used to other sentient alien species, but there's gotta be something they find peculiar (for better or for worse). What do they think is weird about this human that most humans would find normal?
What would they think of human history? How does their planet and galaxy's history compare to Earth's?
Idk just the thought of a very homesick Yuu talking about Earth stuff they remember learning to the Heartslabyul crew and how, despite all of its problems, they miss the familiarity of it. They miss their family. They miss their friends. They miss their favorite hobbies and places. They want to go home.
How did this ask go from world building questions to Yuu angst...?
they absolutely would be weirded out!! most alien species are at least a little weirded out by each other (at first) just because of general cultural and body language differences. Yuu is a little bit more special because they are the first human in the wider galaxies to make contact with sentient life outside Earth!!!
luckily, humans are pretty good at picking up cues even in non-humans.
i think coffee and spice consumption would probably freak them out a bit. (NOTE: the species native to Shaftlands/Pyroxene and the Scalding Sands can eat capsaicin, but most other species can’t and is considered a mild to mid tier poison. there are alternatives, they just don’t taste super good to humans lol)
a big one that would freak ALL of them out would beeeee persistence hunting! persistence hunting in nature is pretty rare, and most of the twst aliens evolved from species that are more ambush/pursuit predators.
heartslabyul (-Cater) would probably also scare Yuu by waiting and popping out in random corners to find them. they’re very light so their footsteps are often not particularly loud either. cast them in a scary movie immediately
a lot of this was pretty heavily inspired by humans are weird/humans are space orcs so totally go check that kind of thing out if you’re interested!! some of it isn’t very applicable to this au, but theres a bit that def can be!!
hmmm… there’s not a lot from twst i can actually go off of since they don’t give us much in terms of general lore i think? a lot of wordbuilding specifically ties into the characters or the Great Seven which makes comparing twsts and our histories a bit difficult 🥲
we do have the fae/human war, but it’s been really hard to incorporate into this au, so i think i’ll have to cross that bridge when i get to it unfortunately :,) i could make in a galaxy wide war with two kinds of species in the same galaxy maybe? i guess we’ll see ;)
Yuu is absolutely very homesick and i could totally imagine them talking about Earth and human culture to the aliens, and often mentioning how much they miss Earth.
the trouble is… i don’t think they can actually go home! with their new knowledge of the outside galaxies and all of the things they’ve seen and done there’s no way the intergalactic federation (and STYX) would let them go home if they were found. the only possible way is if their memory was erased, and the only thing that has the capacity to do that is destroyed in book 6. would they even be the same person if they did somehow go back to Earth? and could they leave their alien friends behind? after all they’ve been through with them?
the good thing (bad thing??) is that everyone else on the Night Raven are in a similar situation. most of them can’t go back to their home planets for one reason or another, and i think they could understand Yuu’s feelings in a way they couldn’t in game. i think it would have to be filtered (or broken through) 15 layers of pride but i think they could eventually sympathise with Yuu and find a new home on the Night Raven.

i want this au to have a happy or bittersweet ending, but i think we’ll have to wait for book 9 in twst first and see what happens there ;)
