Given the fact that was the eastern borderlands of the Franks and covers roughly Belgium, Luxembourg, and the Netherlands I’m gonna assume the only connection to Austria these territory has is the Aust portion. Also Austria evolved out of Otto the Greats Holy Roman Empire not the Carolingian Empire though admittedly it does have its roots in Charlamagnes campaign against the Avars.

Point is East is relative, the East Coast of Asia is to my West.

It makes sense when you consider that the Osterreich was a border princedom against the Magyars originally before growing into something far more notable. Same thing happened with Brandenburg and Pomerania with the Old Prussians.

In the mildest defense of Rowling she actually did put it into the books that you can’t just poof food into existence. Summoned food has no nutritional value and duplicated food has its nutrients halved, the food was cooked by house elves and teleportex to the dining hall. It’s explained somewhat similar to how folks can starve on lean meats, you are physically full but without something in addition you’ll just starve to death, it’s actually an element of the last book that the main cast are slowly starving to death for a bit.

Though none of that stops them from producing food via other magical means such as what amounts to magical automata. Pretty sure the car in book two had animalistic sentience by the point of the spider subplot, so there’s nothing stopping them from making magic farming tools that do that all automatically. They really should be a post scarcity society, but well Rowlings a shit world builder.

Hence why Lilly triggering some time of ancient ritual or creating a new ritual to counter the killing curse makes sense to me. Mind you Rowling is shit when it comes to in depth world building, but what she does set up even unintentionally is that the wizarding world is on decline possibly in a 40k type way where they are simply losing more and more knowledge after each generation. Having Lilly create or activate an old ritual either intentionally or not doesn’t remove the sacrifice it simply remove Rowlings stupid power of love trite. The power of love is still present but more symbolic in Lilly using her and possibly James as a catalyst to protect Harry.

Also I have accidentally pointed out the flaws of Rowling writing just to nerd out about magic systems. I don’t even dislike soft magic it’s just Rowling did it badly, aight gonna go read Yojou Senki.

I always liked the idea the it was actually just blood/death magic and everyone was just too ideologically blinded to see that sacrificial magic was used for good. It makes sense that Voldemort would be blindsided that one of Dumbledores followers used a bit of dark magic, imagine fighting someone who refused to use chemical weapons only for them to decide to use a nuclear landmine on you in particular.
