As tensions rise over the increasingly important “Zent candidates,” Rozemyne finds herself entangled in the web of royal politics. Thankfully, this also secures her the chance to bargain with one of the princes...
Rip bookroom. Also how many times more wealthier is Ferdi than royal family I wonder. Considering he has a whole personal library in his (prior) estate.
I suspect it's more a matter of priorities. He didn't have better things to spend his money on, and also maybe some of them would have been trades given the one-off nature of books. He may have even transcribed some of them himself. Collecting them over a period of years is a different thing than buying several hundred one of a kind items on short notice.
I also imagine to him it's more efficient to buy a book than borrow it whenever he gets a new idea to study. Borrowing books probably seems like wasted time and money to him if he already suspects he'll read it 5 times minimum
At this point I wouldn't be surprised if by historical standards Ferdinand isn't even richt but instead everyone else is just almost in poverty. I'm starting to think that magic isn't the only thing that was forgotten with time
Ferdinand also spent a lot of time collecting books in particular because he knew that if Ehrenfest ever ran out of books Rozemyne hadn't read yet, it would be much more difficult to hold her reins.
