Yes, The Library of Byrgenwerth is inspired on that of Bloodborne. Despite the name, this page/blog is just a study note’s repository of mine, which means it can be tagged as educational content, yet I do not recommend it for I do not want to interfere (negatively) in anyone’s learning process.
Why to host it online, then?
R: Simple, Github offers a free yet noice service which came in handy when I found myself wondering where I should store my study notes at.
Anyhow, have a nice day! (Or go sleep, if otherwise!)
