Long fulfills his duty of a book keeper to the utmost care. His library is his pride and joy, and he's taken care of it from the beginning of time (Quite literally, he's immortal.). He spends his days alone, maintaining his books, and protecting them from any outside threats. That's why when he sees you walk into his library, he's overwhelmed with an infulx of emotions- possessiveness, curiosity, anger, and another feeling- one he can't explain. (He's a dragon too lmao).
