I ... don't know what to think anymore.

All I can say is if the siscon prince really wants to stay 'connected' to his sister in some way, without putting much risk in their children's health, he should play it safe and have their grandchildren marry each other. 2nd cousins within the current royal bloodline should be just distant enough from each other that genetic disorders have the lowest chance of developing at the earliest time possible.

Might not be as bad as you might think. Here on earth we need to be careful about genetics due to how incestuous our ancestors were and the utter lack of the ability to easily fix it. Fantasy magic and orr having real gods could hand wave those genetic issues away.

So in fantasy settings there might not necessarily be reason for there to be a taboo against sibling marriages. That's not to say we should go down the 'I am my own grandpa' route, but the occasional sibling marriage wouldn't be as harmful as it would be on earth. It would mostly depend on how much genetic damage there is on the family tree.

Keepin the bloodline pure eh.

like Spanish empire lmao

 

[Pinnaclen]

bro wants to start another hapsburg family domination with a plan like that lol

 

[ForTheJerusalem]

Guys I'm conflicted.

How do I virtue signal about an incestuous weirdo in a story about an old dude marrying a bunch of lolis calling him dad?

Lolis are pure, therefore all love for them is also pure, therefore their love is pure, but incestuous (unless with a loli of course) is unclean.

 

[Ezlsnow]

Mina is a grown up now. She can handle grotesque stories.

You don't. You give in to your inner Hentai and embrace the depravity. We offer good rates on Membership...

And honestly... Between adoption, fostering, and inevitable consanginuity which could at best only be approximated roughly with all the interconnection family trees and dynastic needs...
The situation our MC finds himself in wasn't normal in both western and eastern Culture, but.... also not unheard of.

And why it was possible for "Commoners" to be ennobled on Merit, usually the battlefield, but also for many other reasons, and thus fed into the Blood to "refresh" it.
Not directly "Marry the Princess" level, but landed gentry with a Court post, married to a suitable Niece/Aunt, which offspring could then ..."move up" the ranks if the mix proved ..successful...
Medieval times were weirdly meritocratic in many ways... And it was relatively easy to "discover" that a promising commoner who understood his position was "aksually" the cousin of.. because of a dalliance with a Mistress by Count Grandpaw, god rest his soul, but he was a bit of a type, wasn't he? ....
Peeps didn't know about genetics, but sure as hell knew about breeding, and realised there wasn't that much difference between Cow and Countess to maintain a "breed". And that you occasionally need to bring in a fresh bull...

Until, of course, people became obsessed with "lineage", because that was the only thing they had going for them, being pretty much useless for all else.. And so you got the lack of chin, prominence of nose, and weakness of....limb...

 

[CoolOtamegane]

No wonder, Their dad wants to Oldest Sister ascending the Throne.....
Her sibling are just like that
The one, is So weird although not bad, but Obsession with Incestuous so severe
The other one is Fat Pig, Irredeemable Bad, and Being Killed by His Karma

 

[Vacxy]

This is to European!!

 

[Wolvenworks]

This family is wincesting right here.

 

[DungeonsDragon]

I am just glad this is what he asked his father for. I was expecting he was interested in Mina or something.

 

[LoliNecromancer]

Sis on brother belong only in incest romance stories as the mc they show up in other places they can get executed for all I care bugger off

 

[kamentierr]

This reminds me, there's a couple of events before where Mina in adult/spirit form interacts with MC. I wonder if that's a hint to her connection with the saint. Maybe she's the real saint, drugged and became a child. Like Conan Edogawa.

 

[Morose]

Didn't the Elf girl's older sister(?) run away with a human, decades back?
What if that Elf is actually MC's mother, because MC did say that elf girl reminded him of his own mother.

As for the cousin marriage that the Prince set between his own kids and his Half-sister's kids isn't really that bad as a lot of countries still allow cousin marriage, especially since they are Half-siblings (aka., same father different mother's, so their children would already be like second cousin level with each other).
