The Librarian

The Librarian
Title: Keeper of the Sunken Records
Role: A small, elderly man who lives in a shack built from stacks of rotting books and scrolls. He claims to be the last survivor of the "University of the Wastes," a legendary institution that was destroyed during the War of Sunder. He spends his days trying to restore and translate the ancient texts that scavengers bring him.
Secret Motivation: The Librarian is actually a "Ghost-Construct"—a magical projection of the University’s original head librarian. He is tied to a specific "Soul-Gem" buried beneath the lake. He is trying to guide the party to the gem so they can "reboot" the University’s ancient magical defenses and protect the town from the coming draconic war.
Adventure Hook: The Librarian shows the party a book that is "screaming." He tells them that the book contains the "True History of the First Brood" and that they must protect it from the Obsidian Scale agents who are currently hunting him.
