It was filled with an array of books, and he then heard some motion. Since lifeforce was dispersed from this place, Alex couldn't really tell if there was really someone there or not. So he decided to check.
To his surprise, there was no one there, only a broom moving by itself, cleaning the area.
"So this is how she cleans the castle," Alex mumbled.
His focus then turned to the book titles. Reading each one, he realized all of it was about this place's history. Nothing he found interesting since he didn't have any plan to stay in the area longer than needed.
After beating Gluttony, he wanted to quickly leave and then go to his goal of building more army and rescuing his father.
Walking through the towering rows of bookshelves, Alex found a peculiar rack.
It was largely empty, with a rune formation engraved around it.
Looking closer, he could see one old book placed on a pedestal, written in real Edonia language, "Alucard's Journal."
