Yes oh my goodness oh my god. Lilia grooming Silver from birth to be Malleus' concubine, while never even telling him that's what he'll become. Silver thinks he's going to be his knight in shining armor, just like Sebek. He is WRONG!! When his father gives him sex ed, it's about how one leaves their eggs within another and they both give the eggs magic until they're big and the shells have hardened enough to leave the egg-bearer 🥰 (I've thought a lot about this. I think about it constantly. Just by the way) Silver doesn't give it a second thought, as far as he's concerned, that's just how it works (and that's all he'll ever need to know, anyway!) And when he's told who he's betrothed to, omg... What a shock. How delicious would it be if he tried to get out of the marriage? It would make Malleus so angry, so much more possessive... He will marry him, in the end, of course. He never had a choice. His father will remind him, before they're officially wedded, that this is what he was always here for. This is his purpose... 🤤

I need you to see my vision in that when I say Maleficia wants to make him a lapdog, I mean Maleficia wants to hold him in the castle at once and strip away all his fighting lessons so he can attend to her, personally, instead. She wants to wake up and see him on her bed, bound and gagged like a tied hog. She wants to teach him to let go of all his unnecessary thoughts, let his queen take over instead. Let her show him the meaning of pleasure and obedience and what his only use is as her human

But, unfortunately, Lilia wants to play papa and raise a strong knight (as strong as he can be, anyway), soooo... 😔 poor lady. She truly is a tortured soul

YES 💕 I'll be honest, I don't think Lilia or the Draconia's have any clue as to what Silver's heritage is, but... Fate brings people together, right?

All the Draconia's feel strange around Silver. Nothing strong like hatred or love, but just... Interest. A magnetic pull. And obviously, they don't see Silver as a threat. He's too young and weak, it's laughable. They just think he's cute :) Malleus and Maleficia both grew to really adore him and find his effort to be useful... Endearing. Maleficia is so jealous of Lilia!!! If she didn't respect him as her general, she'd happily steal Silver away to be raised as a lap dog instead of a useless knight 🥰

(EDITED and REPOSTED)
AAA thank you for asking very much :) the darker ones were definitely easier to come up with ideas for than the fluffy ones lol!!!

Fluff:
-Does it need to be said... Malleus STUFFS Silver with the most delicious treats. Especially when he was younger <3 macarons, pies, pastas, steaks, all of the HIGHEST quality. It drives him mad that the only thing Silver ever asks for is mushroom risotto 😭 he could give you more!!! He could give you better!!!!!!! Silver's still so cute about it though 🥰 he gives the softest little "thank you my lord" before digging in so fast and desperate, he puts Sebek to SHAME 🥰 Malleus loves to watch him eat <3
-They would adopt :) I don't like kid tropes that much personally but they would definitely be the first ones to adopt the strange little kid who ended up stranded in their kingdom. In my heart, it would be beastfolk or merfolk. Two lovers of different species bringing in a kid of yet another species 🥰 (oh my god. Wouldn't it be so cute if their kid was beastfolk of some sort of forest animal... Silver was practically raised by the forest and now he's raising a little kid with traits of those same forest animals 😭)
-They don't do a lot of lip kisses? They rub their noses against each other 🥰 they feel out each other's features, ghosting fingers over the dips and curves of their faces 🥰 they rest their foreheads together 🥰 oh my god, Silver gives Malleus butterfly kisses on his neck and Malleus purrs... 😭 that isn't to say they never do lip kisses, obviously!! They'll only see it as something romantic if it's a french kiss, though (don't take it too weirdly, lip kisses are just platonic in my family)
- (BONUS) Malleus and Silver both purr. It's a fae thing and Silver picked it up. End post <3

Dark:
-If the nation is at war, Malleus will send Silver to the front lines. He'll regret before he's even done it, and he'll regret it more afterward. He tried to avoid it by saying Silver had his role at Malleus' side, but Silver, ever eager to please and give everything he can, begged him to place him where he could actually be most useful... He didn't want his country to burn while he did nothing :( He would threaten suicide if Malleus refused him, honestly (not that he would follow through, but at that point, Malleus would still concede). Silver dying on the field would be the last straw for whoever they're at war with. They won't last against Malleus' wrath...
-Less of a headcanon and more of an au, but come on. Every single au where Silver is arranged to marry Malleus from birth <333 so delicious. Lilia is grooming him for the role really early on, way too early. I'm saying he would cast magic charms that widen and self-lubricate his little butt hole starting when he was 5... Well, he knew he would grow up fast!! The sooner he gets these things over with, the better, right? He's only 12-14 when Malleus actually elopes with him, too... It definitely adds to it if they know that Silver is a prince from another kingdom. It's a power play. What better way to show dominance over another kingdom than for the future king to have their beloved lost prince, barely entering puberty, whimpering and crying while Malleus stuffs him...
And despite the fact that he was groomed for it so early, they'd probably forget to tell Silver what exactly is going to happen too 😭 I generally believe that Silver was so interested in knighthood and training as a kid that he wouldn't think to ask questions about love or sex, so he goes in BLIND. One day he's playing with Sebek in the woods, the next he's told to dress in these fancy robes and woaaahh what do you mean he's moving into the castle? What do you MEAN he's marrying Malleus??? Ooh... The poor boy.
-Silver has a lot of scars from when Malleus first tried to handle him as a kid. Burn marks, claw marks, even spots where he got practically butchered by Malleus' horns. Baby boy is lucky for modern magical medicine 😔 Malleus doesn't even regret it. While Silver was a baby, he definitely cared a little for the kid, but he was very much "well, he'll die soon anyway..." about it. By the time he cared enough about Silver to worry about hurting him, he decided that his past scars were all very attractive. He left his mark on him!!! He's his!!! Most of them were formed before Silver can remember, so he can't properly resent Malleus for it. He just wonders why he shivers so much tapping the tip of Malleus' horns....

For Silver's birthday, Malleus waits for the stroke of midnight to wish him happy birthday. If Silver won't wake up, then he'll just give him lots of happy birthday kisses in his sleep <3 He tries to make the day as enjoyable as possible, giving him tons of luxurious gifts and taking him on a gorgeous, fast-paced flight across the island. Silver would honestly prefer something more low-key, and has no idea what to do with these expensive, antique books ("I guess I can use them for weight training...?"), but he still thanks him, saying he doesn't deserve all these things <3 Malleus also takes care of the catering, no Lilias allowed in the kitchen!! In general though, I think Malleus would be sort of melancholic on his birthday. It's the day to celebrate his little beloved, but it also means one less year with him </3
For Malleus... Eheh. Silver will ask Lilia beforehand what he should get Malleus, and you know Lilia is already dragging out the fancy lingerie and bondage (Lilia, why do these fit Silver, and why do you have them....) He'll prepare himself just for Malleus <3 Dragon boy is going to town all morning long, Silver's ass is STUFFED by the time they're done. They take a bath together, and it's so soft and peaceful <3 (until Silver mentions that he also got Malleus a gargoyle for his birthday, getting Malleus in a fit because it was NOT a gargoyle...)

That said, I don't have any notps or anything for twisted wonderland. There's plenty of ships not listed that I still enjoy looking at content for, they're just not the kind that I actively seek out <3

Omg this will be long thank you for asking, I think about a/b/o a LOT <333

First off, I really like omegaverse for the power dynamics! I like it when it's not only a strict societal rule that omegas are submissive and alphas are dominant, but biological as well. I like to think that if an omega isn't constantly being submissive in their pack, then they'd go into a very heat-like headspace where they can't do anything but submit. Same for alphas, if they aren't constantly dominant, they'll go into a rut-like headspace.

With that in mind, I'm not a big fan of betas being the "normal people" of the au. They don't get to escape the biological and societal pressure <3 In fact, they get it worse in a way. In their packs, they have to stay at a balance where they're both submissive and dominant. Too submissive, they go into a rut-headspace. Too dominant and they go into a heat-headspace. You get the idea ^^ When they go off-balance, it's probably not as bad as for omegas and alphas, though.

For NRC, I imagine that each dorm is supposed to act like a large pack with smaller ones within it. The dorm leaders are traditionally supposed to be the head of the entire pack, not belonging to any specific smaller one. To symbolize independence and leadership over the whole dorm, they sleep alone, while the smaller packs each share a room together. Most people know that they really belong to this or that pack, though <3

I'll give a run-down of how things are in each dorm :)

Heartslabyul: Riddle is an omega, it's just his fate 🥰 he struggles to match his biological need to be submissive, so it's not uncommon to find him stuck in his room with an alpha or beta late at night because he got in a headspace again... Usually Trey or Cater (who could be alpha or beta IDK). Ace is an alpha, Deuce is a beta. Ace teases Riddle for trying to be some dominant omega a lot... I think Deuce used to have issues going into a heat-headspace with how hard he tried to be dominant. Since going to NRC and changing his ways, though, he hasn't had many problems :) he's a very submissive and sweet boy for his seniors and dorm leader <3 Trey, Ace, and Deuce share a room as a pack while Cater goes around to different ones. New one for each night... Sometimes he's not even spending the night at Heartslabyul ^^ He tries to deny how often he spends the night with Trey and Adeuce, though

Savanaclaw: Leona is an alpha yeah yeah yeah. Ruggie is an omega, and I think Jack would be a cute beta that most people mistake for an alpha. Ruggie is very blatantly spending all his time in Leona's room, and eeeeeverybody knows they have something going on. Jack..... Hard to say where he is. Maybe he spends his time in other dorms with the other first years 😌

Octavinelle: The mers don't have the same a/b/o biology, so taking the potions and suddenly having these weird urges is quite the adjustment for them! I think these three are doing okay, though. Azul is an omega by my bias <3 everyone thinks he would struggle the same way Riddle struggles with being too dominant, but he has a way of talking and moving that is pretty subtly submissive. He'll bow in look up at you with big pleading eyes like "won't you please take my deal??" Yeah he's doing just fine :) Floyd and Jade are alphas by my bias... I think Jade acts very submissive so he purposefully goes into a rut-headspace, honestly. He thinks this weird human biology is just so much fun to play around with! Jade and Floyd sleep together, and really enjoy dragging a third little omega into the room with them <3

Scarabia: Kalim is an omega yeah yeah yeah Jamil is an alpha yeah yeah yeah they sleep in the same room for safety reasons ECT ECT. As far as dynamics go, they bounce off each other very well with few issues. Kalim is the one in charge and Jamil is the servant, sure, but Jamil knows what he's doing and Kalim reeeaally can't help how he submits to him so easily 🥰

Pomefiore: Difficult to say for Vil... I'll go beta :) I imagine the movies he acts for peg him as an alpha pretty often, which frustrates him a lot. Good thing Rook is an alpha... Omg and Epel is the cutest little omega too <33 he hates his biology for sure for sure jshdhdgd These three are such a sweet pack, aren't they?? They're not kidding anyone, Vil is super blatant about which pomefiore pack he belongs to 😌 Epel didn't want to be there at all, of course, forced to room with Rook by Vil. I think he warmed up to Rook pretty quick, though.... Thinks about them.......

Ignihyde: Idia is so pent up omg. Could you just imagine if he was an omega with me.... He's so desperate for a dominant alpha, he makes Ortho fill in the role 😭 Nobody on campus knows that he's an omega, they just wonder why Ortho so easily takes charge of every situation he's in! He even gives out orders, and woah, did he just call someone a silly little rabbit?? Idia, get your brother's code under control...

Diasomnia: omg omg omg. Malleus is the only alpha in his pack, but he ends up so busy, and he still hasn't taken any of Lilia's hints that Silver and Sebek should really move into the castle already to be closer to their pack's alpha... Those three get so fucking needy and submissive and docile the second he's entered the room omg 😭 (me being as indulgent as I possibly want WHATEVER) Lilia and Sebek are omegas in my mind while Silver is a beta, yea... Silver has to take charge a LOT, he is working double time around here 💪💪 doesn't help that his classmate best friend is voted-most-submissive-omega Kalim... He's so starved and desperate for someone to put him on his knees yea..... Things are a little better in NRC since they're in closer proximities, but it sure would be nice if Malleus wasn't always wandering who knows where to look at rusted architecture 😭 He's the WORST please... It's not even on purpose, he's just that dense 😔

Thank you for the ask I had such a fun time writing all the out 🥰🥰🥰
