15Redstones

Eglantine and Anastasius implied that underage marriage would be possible with the Zent's explicit approval

Both Lutz and Deid accidentaly insulted an archduke of Ehrenfest lol

It's a reference to Aella's statistical analysis of how many people came to her birthday

What Hannelore doesn't see is that Ferdinand is just as much of a research gremlin

Ferdinand would've been difficult to detect since he was so close to her own mana. Gervasio was in the detectable range and noticeably different. Then after getting divine mana she was out of anyone's range, and only after most of the divine mana was drained was Ferdinand in her range and different.

The replenishment hall magic tool doesn't look like a big feystone. The foundation does.

The feystones would only be needed in an emergency. For regular discharging, she should be using the replenishment room.

She did give him this order: “Listen to me, Ferdinand... You have devoted so much of your life to that promise you made. Going forward, I ask that you focus on your own dreams. No matter what Sylvester, Lady Hannelore, or anyone else says, do not surrender. Do everything in your power to secure the future you desire.”

Hartmut as the High Priest already interacts with the soldiers. Gunther knows he's loyal to Rozemyne, and Hartmut knows Gunther is her dad.

In this case you'd still need a way to know who the photographer is and whether they can be trusted. The photographer at the beginning of the chain can sign anything, regardless of if it's a real photograph or edited (or a real photograph of a staged scene with fake location/time data). The cryptography system could only tell you that the image originates with the same person or organisation who is associated with a specific cryptographic key.

How would they be made secure against faking?

If the cryptographic key itself was extractable, it'd be easy to sign fake images with just a bit of custom software.

If it isn't, there's still workarounds. Buy a professional photography camera, disassemble it, extract the chip that does the signature, feed it fake GPS and image data, and you have a modified image signed as legit. A country's intelligence agency could easily do that.

Even if the camera was made completely unmodifiable, you could put it in a Faraday cage, feed it a spoofed GPS signal for fake date/time/location data, and take a picture of a high resolution screen showing your photoshopped image.

Building a system where end users are told "this image is cryptographically confirmed to be legit" just makes it easier to convince users that your fake images are legit.

That's not in the packaging, it's in the rind of the cheese itself. The labels are also written on the cheese itself.
