Zaddar needs me to find the Book of the Dead, an ancient tome used by necromancers to summon the dead and place curses on the unfortunate. Zaddar feels that this antiquated tome of undead magic still exists within the graveyard and must be found to repair the ward. I must search the graveyard for this tome, starting with those scoundrel grave robbers that make a habit of unearthing the dead. These grave robbers typically work at night, so I should seek them out then.
