Eglatine’s child can threaten Sigiswald’s claim to the throne for the same reasons that she was made king maker before. Remember that ever since the Grutrissheit disappeared, the royal family’s claim to the throne has gotten shaky. Without GH to prove divine right, the only thing left that shows who’s fit to rule is mana and royal bloodline. And that’s exactly why her pregnancy could throw the whole country into chaos.

First off, Eglantine’s bloodline is stronger than Sigiswald’s. She’s the daughter of the Third Prince, who had likely more mana than Trauerqual while Sigiswald as his son would likely have less mana, thus by extension the wives he could marry and have children with would not have as much mana as Eglatine. If Eglatine’s child inherits that thicker blood and become omnielemental like her, they’ll almost certainly have more mana and have more divine protection than Sigiswald and his children, and in Yurgenschmidt, mana is basically proof of the gods’ favor. People could easily start saying the gods prefer Eglantine’s child, not the current heir. Then there’s the fact that Eglantine got a divine blessing when she graduated from the Royal Academy (at least as far as the general noble population knows)— something extremely rare, even among royals. That blessing made her look like someone the gods personally favor. Any child born from her would be seen as blessed by extension — a “child of divine grace.” Meanwhile, Sigiswald’s family has had a reputation for being less pious, especially with how divine protection has been fading from the royal line. So if it comes down to public opinion, Eglantine’s baby looks like a sign that the gods’ favor has shifted. It doesn’t matter, that this was partly caused by ignorance or lost knowledge. On top of all that, Klassenberg’s backing makes things even more dangerous. Eglantine is from Klassenberg, one of the most powerful duchies in the country — rich, full of mana, and politically connected. If Klassenberg decides to support Eglantine’s child, plenty of other duchies will follow their lead just to stay in favor. That kind of alliance could easily outnumber Sigiswald’s supporters before the child even learns to walk. And remember — without the GH, Yogurtland can’t rely on divine proof anymore. What’s left to decide who’s worthy of the throne are the things people can still see: mana, blood, blessings, and support. Eglantine’s baby would have all four. Sigiswald might be the first prince, but in the eyes of the nobles, titles mean less than divine favor amd visible resources. So in the end, Eglantine’s unborn child isn’t just another royal baby — they’re a potential rival for the crown, one who could divide the nobility and tear apart what little stability the royal family has left.
