Rise of the Lich King, Chapter Three

Blizzard's official World of Warcraft community website has been updated with the third and final chapter of the ongoing "Rise of the Lich King" short story that leads up to the game's Wrath of the Lich King expansion pack.
All of Lordaeron rejoiced at Prince Arthas' triumphant return from Northrend, but their elation was not to last. Not long after Arthas knelt before King Terenas, the former paladin thrust Frostmourne into his father's heart. At the Lich King's command, the fallen prince went on to murder his mentor, Uther the Lightbringer, and claim Kel'Thuzad's remains. When Arthas had finished, Capital City, formerly one of humanity's crown jewels, had been reduced to a silent wasteland of death and despair.

The death knight Arthas then marched his ever-growing army of the undead into the forests of Quel'Thalas, slaughtering the elves in his path as he smashed through the gates of Silvermoon. Arthas laid claim to the legendary Sunwell, using its powers to raise Kel'Thuzad as a lich and leaving the high elven lands utterly devastated in his wake.
