Author's Notes: Alright, so I have had this story making it's rounds through my mind for awhile now, and after being hit with a muse something hard tonight (at the time of starting this), I thought it best to put fingers to keyboard and get to work.

Now, before I start; I would like to say that this story is a spin off of another story written by another author by the pen-name of Zezin. Feel free to check out their story here!

Now, this story will be taking a different approach to the concept. It should be noted that there will be numerous changes in this spin off, compared to it's original source material. So I encourage everyone to read the original story first!

Dead Winters Reign

Anna and Kristoff trudged behind the elder rock troll as he lead them into a large cavern, hidden deep away behind a series of winding tunnels. Sven was none to happy to have to wait outside the cave, but due to his large size, was forced to comply. Even Olaf was asked to stay outside, due to his creation from magic could potentially destabilize the flow inside the cave. The decision to reach out to the trolls did not come easy, as both felt they had already asked too much of them between the incident no more then two years ago, let alone Anna and Elsa's childhood accident. However, Elsa had been missing for over a year, with no clue as to what could have happened to her.

She had announced she was going out for a walk, and had never come back. At first glance, it could be assumed that the Queen had grown weary of her crown and had left the kingdom in the hands of her sister and her sister's lover. Though, when the scouting party returned, they reported that her footprints merely disappeared not far past the front gates, as if some mystical force had just swept up the Queen and disappeared.

"We have managed to trace her magic to an unknown realm to us." Grand Papi stated, giving Anna a slight start from the sudden noise after so long in silence. "We had almost missed it. Your sister's magic was over shadowed by an extremely dark source of magic."

"Do you know if she is alright?"

Pappi was silent for a moment, stopping in his tracks as he turned towards the young princess.

"We can not tell for sure." He began, uncertainty in his voice. "Her magic is intact, but weak. It could be from the dark force that has surrounded her or worse. So I ask that you prepare yourself for what ever it may be."

Anna's breath hitched in her throat at the thought of her sister being severely hurt, or worse.

"We shall begin the ritual shortly." Pappi continued. "Should it work, your sister will be among us once more."

"And if it doesn't? Anna asked, though afraid of the potential answer.

"Then she will be lost forever."

Icecrown Citadel

Footsteps echoed throughout the corridors of the massive fortress as a lithe figure made her way through the halls, towards a set of massive doors. Her long purple robe billowing around her as she moved with grace. Aside from her attire, a ritualistic dagger adorned her right hip, while a large tome occupied the other side. Filled with dark spells she had become well versed in over her year long apprenticeship under the King of the damned, and rising through the ranks.

It wasn't always like this of course. In the beginning, she had been hesitant to fully delve into the dark arts. She had both been awed by the power of necromancy, and frightened by it. Studying the written literature's on rituals and spells, but only just teetering on the edge. At least until that fateful day the Lich King had opened her eyes to the power she was denying herself.

A dark smile graced her lips as she recalled that fateful day. After her eye opening meetings with the king of the damned and a bit of soul searching of herself, she had resolved to take the plunge. Lady Deathwhisper had been outraged at her demand for a test subject to hone her skills, but obliged anyways. If only to appease the Lich King.

From that day onward, she had become drunk with the power of death. The thrill she got from extinguishing the life of another, and raising it, and bending it to her own will was intoxicating. Not to mention the added perks of combining her necromancer powers with her already existent ice abilities.

Arriving at the massive set of doors, she pushed them open, and knelt before her king.

"You summoned me, my Lord?"

Yet another thing that had changed over her year long stay. At first it felt humiliating to address him as such, but now; it just felt natural. He alone held absolute power over the undead scourge she was helping to build. One captive at a time. Horde. Alliance. It made no difference to her. She would sacrifice them and raise them in the name of the Lich King and bolster the scourges ranks.

"Ah, Elsa." The Lich Kings voice echoed off the walls as he turned to address his most prized student. "I was just thinking about you."

"That's a first." The ice queen chuckled.

"Indeed." His voice betrayed no evidence of being annoyed by her remark. "There is something I wish to show you, that I believe you are ready for."

Giving only a slight motion to signal her to follow him, he set off out the room and down the hallway she had just came from. Not wasting any time, Elsa quickly fell into step behind him. Managing to just barely keep up with his long strides. At his pace, it didn't take the two long to reach the forge room on the same level. Skeletal blacksmiths filled the room as the sound of hammers banging away as weapons were being forged from pieces of steel, to useable weapons for the scourge soldiers.

"As you may have learned from your studies under Lady Deathwshiper, rune weapons are among the rarest and most powerful weapons in all of Azeroth." He began. "But, what if we could mass produce them?"

"To be honest my lord, I have only skimmed over the weapons section." She admitted. "I have mostly been focusing my attention on my spells and rituals."

"So I have heard. Lady Deathwhisper boasts of your ability to summon dozens of skeletal warriors at a time. Truly impressive."

"Thank you, my Lord." Elsa replied, a little flustered by such a compliment from him. Something he rarely, if ever did.

Arthas turned and grabbed a dagger from the stockpile of weapons laying on the table beside them and thrust it into the massive forge. After a few moments, bluish flames erupted from the forge. The young necromancer could feel the magic that radiated from the forge. Slowly the flames began to die down, and Arthas reached in and grabbed the newly rune forged dagger.

"Behold, Black Ice!" He exclaimed, holding out the weapon towards her. "A reward for your loyalty and feats of strength during your apprenticeship under Lady Deathwhisper."

Elsa looked in awe as she slowly grasped the runed blade. What was once bland and cold steel was now glowing with an awe inspiring bluish hue as the runes danced up and down the spine of the blade. Small skulls adorned the handle and guard, signifying her power over death.

"It's beautiful." She breathed, looking up at the Lich King, her eyes widening in shock as he removed his helmet for the first time in front of her, revealing his flowing white hair and pale face. His eyes still glowing with the eerie whitish blue hue.

However, she didn't get long to savor the moment as she felt a tug at her core. Something was pulling her away. Away from Azeroth, away from Icecrown, and away from Arthas. Her eyes horror stricken she reached out. "Arthas!"

Then she was gone, only an anguished, unholy yell that shook all of the Citadel remained.

Cave

"Did it work?" Anna asked as the bright light began to fade away. Leaving only darkness in it's wake.

"Calm yourself young one, and look to the center of the circle." Pappi smiled, clearly relieved that the ritual had worked.

Slowly, the young red head turned her eyes to the lone figure crouched in the center of the ritual circle, clutching what appeared to be a magical dagger in her hand. Holding it in a defensive position.

"Elsa?" Anna called out, slowly approaching her older sister; resisting with all her willpower the urge to just run and embrace her wayward sister.

For a handful of breaths, the ice queen didn't move. Letting her eyes adjust to the darkness. Her ears focusing in on the voices around her. They sounded familiar, but she couldn't place where she knew them from.

"Anna?" She asked softly. Casting her eyes towards her approaching sister.

"It's okay Elsa." Anna continued. "Please give me the knife."

"Dagger." She corrected the red head.

"I'm sorry?" The younger sister blinked confusedly.

"It's called a dagger." Elsa said, holding it close to her chest before securing the rune dagger to her belt, along side her other ritual dagger. "And it's fine where it is."

Standing to her full height, Elsa pulled her hood over her head. Mostly so no one could see the markings on her face. She would have to find a way to hide them later, for now she wanted time to herself.

"We should return home, I suppose."

"Alright." Anna replied, watching as her sister began to walk away. A little put off with how distant Elsa appeared to be right now.

"Give her time child." Pappi offered. "She no doubt has been through much, and will need time to heal from her ordeal."

"Thank you again, Pappi." The red head stated, before turning and taking off after her sister; leaving Kristoff behind; whom only shrugged and followed after her.
