Prologue: The Frozen Throne
It wasn't how he expected it to be. In his confusion, Arthas could not tell if he was stronger or weaker now that he wore the Helm of Domination. He sat on the Frozen Throne and stared the frozen wastes.
"Now we are one..."
He immediately recognized the whisper. It was the same. All the pain; the misery came from this voice. Along came power though, power he never even imagined in his past life as a champion of light. The voice was still whispering, but he could hear the whispers now louder than ever.
All that time since Ner'Zhul corrupted his mind, Arthas obeyed and followed his orders, bringing death to all who came in his way. Not that he could do otherwise. The hunger of Frostmourne, his cursed runeblade was his also. Now, his master's call brought his before the Frozen Throne. After he shattered the icy prison of his master, he wore the Helm of Domination and merged with the soul of Ner'Zhul
In an unconscious move, he laid his head back on the throne. He soon realized the dire state his master was when the Lich King called him from Lordaeron to the frozen wastes of Northrend. Now everything made sense. But why, even after he wore the Helm of Domination, the new Lich King was still weak?
"It will take time... But our powers will rise day by day... This world will succumb to the might of the Scourge. All of them will serve the Dark Lord... Eventually..." The whispers of Ner'Zhul continued.
He disgusted this weakness. His slowly moved his right arm from the throne and rested it on his chest. His heart was still beating. With every beat an image of a young, blonde boy flashed in his troubled mind. The boy had an angelic face, with bright blue eyes and a big smile that annoyed him. The face seemed familiar, but he couldn't remember if he had ever met the boy; neither in his past life nor as a Death Knight. He took his arm away from his chest and the boy disappeared. Again; he moved his arm towards the chest, but now he touched the open wound with just his fingertips. The boy reappeared. He could even hear it now, yelling from a distance.
"What happens after people die, father?"
"Their souls go with the Light, son."
The man's voice was a familiar one. The sound of it made his heart beat faster, thus keeping the image of the boy was standing before a grave more clear. The boy's identity was still unknown, but the man besides it wasn't. It was his late father, King Terenas II Menethil. Arthas remember the moment he thrust Frostmourne into his father's chest in the throne room. He removed his fingers from his beating heart once again.
This time the words came form his runeblade, Frostmourne. His father's trapped soul echoed in his head:
"It's never too late my son; you can still go after the Light. Forgiveness-"
With a swift move he drove his hand through the open wound in his chest, grasping the beating heart. He felt no pain at all.
"Weakness ...disgusts me!"
Yelled with his otherworldly voice while tearing the heart out from his body. Holding the still-beating heart, he turned his face to the sword.
"I see only darkness"
The heart then ceased to beat, and Arthas turned it to a crystal. Now he sensed that he had to recover. Ner'Zhul was in a much weaker condition than Arthas imagined while he climbed the endless steps of Icecrown. There was a war raging on in Lordaeron, and his grip on the undead was weakened. There was also much work to be done there, in Northrend. A whole Citadel had to be constructed.
The Lich King rested on his throne and let himself fall asleep. It wasn't a calm one.
