Qualifications of a Librarian location (Ereonnor)

Clue

Partus the librarian said hello with a tremor in his voice, and the head librarian answered him curtly. "Your job is to look for these books." Partus looked at the note given to him by the stern head librarian and started to read the book titles on it. "Elgacia Encyclopedia? Great! I can do this!" "Haha... What a fool. I wonder how long this one will last." Partus looked around, wondering where that voice came from, but he didn't see anyone. "Is someone there?" "Darn! You got me. I guess I have no choice." Young Lazenith Retto was crouching in a corner reading a book. He stood up and looked up at Partus. "Making you look for the encyclopedia is a test for all the new librarians." "A test?" "You know the Elgacia Encyclopedia is a very old book that contains our history, right? The head librarian put a spell on it. Its location changes every day. The new librarians that fail to find it... Well, they get kicked out of the Library of Honor." Partus looked around the library bookshelves, packed tight with books, and sweat dripped down his spine. "These things are supposed to be difficult anyway. Good luck." I should look for the book in the Ereonnor Library of Honor.

Story

After many days, Partus finally handed the book he was looking for to the head librarian and spoke. "I think I know why you told me to find this book. I won't forget the sins and history of the Lazeniths. I will fulfill my duty as a librarian to preserve the precious knowledge in the Library of Honor." The head librarian gazed into Partus's determined eyes and answered. "Congratulations on becoming an official librarian of the Library of Honor, Partus." Young Lazenith Retto overhead this conversation between them. His eyes met Partus's eyes. Partus spoke gently to Retto.
