Elsa stood in her newly built ice palace, panting heavily from her exertion. The last words of her heartfelt song reverberated through the halls, making the ice shiver with the words. Unbeknownst to the snow queen, her song had traveled further than her castle. It echoed through the surrounding mountains; the distance it traveled made the words sound more eerie and haunting. Through the raging snow storm it carried, arriving at last at a very different castle.
Through black-blue stone walls of bleak stone the song carried, bouncing off of walls lit by the sickly glow of ice. It passed through banshees and spirits, dodged ghouls and geists, and made death knights sneer in disgust at its innocent tone. The abominations, on the other hand, giggled at the words of the song.
Unlikely though it seemed, the song managed to reach a throne of ice situated at the top of the citadel - carried, perhaps, by a magic greater than frost or death. Its haunting tune pierced the ears of an armored figure who sat brooding upon the frozen throne. Startled, the man - if he could still be called such - cocked his head to listen. At first the melody made his lips curl in revulsion, but as he listened to them the man began to slowly nod.
Beneath the citadel, deep in the bowels of the earth, a frozen heart began to thaw. It was not much - but it was a start.
