It's quite an impressive collection, row upon row of books towering above you. It would take you years to get through them. Decades, even.
Luckily, you have a solution.
Stretching your sleeve, you run along the shelves and hoover up everything within arm's reach. Your merry jaunt, interrupted at one point by a little man with a blowgun who reacts rather poorly to having it shoved down his throat, takes you over tables, up the little stairways, and deep into musty corners where unwanted tomes have piled up. There's some you can't reach without a ladder or unfeasible amounts of parkour, but it won't hurt to save them for later. Not like you can do the usual thing and burn the castle down when you're done.
Although the Powder Kegs could probably whip up something that melts stone with a little time and no supervision.
You find an unlocked chest near the end of your journey around the room. Opening it reveals a red leatherbound book adorned with the same sigil you saw on the carriage. You crack it open; perhaps it contains secret information, left here during Logarius' purge so as to escape the slaughter.
You flip through a few more pages, squinting.
These people had terrible handwriting.
Giving up, you shove it in with the rest of the bunch. You'll come up with a cipher or something eventually.
Beside the chest is a pressure plate elevator, which takes you back to ground level. It opens up within spitting distance of the entrance and you take a moment to admire the pile of Bloodlicker bodies you left behind before heading back up. Stairs take you to the next level of the library, where narrow footbridges span the gaps in a rather lovely but terribly hazardous arrangement. Health and safety guidelines are powerless before vampiric might, apparently, just like their beloved book collection is powerless before your sleeve-based thievery.
After pummeling a few more hunched men, save for another team player who simply ignores the hubbub and diligently restocks the shelves, you take an appreciative stroll around the room. The filing system remains alien to your eyes, but every book you can find is in excellent condition. It's always nice when evil aristocrats cultivate proper respect for the written word.
What they didn't cultivate proper respect for, apparently, is reasonable architectural connectivity. You have to leap up to the third level, as there's no nearby ladder or stairway to bridge the gap. They were vampires, to be fair; probably set it up like this so they could feel badass jumping around to get to different books. It does, however, beg the question of how the servants got up here. Maybe the Vilebloods threw them up to their posts at the start of every workday.
Following another book-scooping run, you take a spiraling stairway through an archway and into the blistering air. As it winds around the outside of the tower, the stone transitions into wood, soaked and creaking beneath your footsteps. That, in turn, deposits you on a gently-sloped rooftop covered in slick tiles just aching to send you plummeting to your death.
Well, not your death. Your massive annoyance, maybe.
With the treacherous footing, you elect to just snipe the gargoyles waiting in ambush. You then spend a few minutes looking for where to go next before noticing a set of fenced walkways between the towers. To actually get to them, someone would have to walk along the edges of the towers' conical roofs and jump down, which would be ill-advised on a good day and absolutely suicidal on one like this. Tuning your brain to the uniquely deformed wavelength of Yharnam architecture, you concede that there are worse ways to stave off an invasion than forcing eighty percent of the invaders to fall hundreds of feet onto pointy rocks.
You remember Djura's comments about a certain individual building "a few bigwigs' mansions" and things make more sense.
You make the journey with only a couple of near-misses, helped along by the bayonets you use to anchor yourself on the rougher patches. The path culminates in a ladder, which in turn leads to a snowbound slope with a torchlit arch at its peak. As with your recent tussle with the Witches, you can smell the impending showdown from a mile away. You also feel your bell burning a metaphorical hole in your sleeves.
At least you hope it's metaphorical. There's a lot of flammable material in there and you would not put it past anything from Yharnam to burn in a vacuum.
