She guards a book lying on a table titled "The Scourge of Lordaeron" which tells of Kel'Thuzad releasing the plague of undeath on the City of Lordaeron and of Prince Arthas' failed attempts to save the city. As he tracks the plague to Northrend, Arthas comes to wield the cursed sword, Frostmourne, but yields his soul as well. The Prince ultimately becomes one of the Lich King's greatest death knights.
