The setting is the summoning day of Mephala, two hundred and four years after the third era. Deep in a cave, unbeknownst to the world, a Khajiit stood in the darkness, lit only by a malevolent crimson light. An incantation took his mortality, along with his morality, or what little was left available for the taking. Apocypha's sister slowly took his soul, morphing it to her own desires. From that malleable mortal soul, molded a being so powerful as to rattle mountains and burn cities. It had siphoned the deceitful energies of the Webspinner into the compact form that is a mortal.
Along with this power, he was given a task. He was to search for and destroy the three last hopes Mundus had for survival. These were the Imperial City, long the most prominent symbol of mortal power in the world, a dragon by the name of Kulaasvolkein, who had given a certain liking for mortals since time immemorial, and the Dragonborn, the most powerful of all mortal beings in the plane of Mundus.
Thus, Mephala created a thread of destiny. That thread wove through the annals of history, passing through time until it struck the crux of the modern era. And to this crux, did it deal the most decisive blow to the mortal plane of Mundus.
That crux was the twenty third of Frostfall, the anniversary of the death of empress Kintyra Septim II, ten years and ten days after the thread was woven. On that particular day, with clear skies turned dark by the absence of the sun, two brave warriors stood against the darkness that is Apocrypha's sister on the peak of the largest mountain in Skyrim, known to most mortals as the Throat of the World. One warrior, a woman with skin so fair as to rival the snow around her. The other, a dragon wearing the skin of mortals, of the name Kulaasvolkein. That princess of war and pale lady stood against the Khajiit that no longer had the soul of a Khajiit.
The sister of Apocrypha, Mephala, had long since prepared her avatar for this battle. He was gifted with even more remarkable agility than he had already possessed, the sword as black as the night sky, the unique ability to cast about crystal thread that shreds through the skin of mortals, and a god-like reserve of magicka, stamina, and durability.
Yet, the two brave warriors fought him. And they fought bravely, shouting out all their will at him, yet they could never fell him. He took the brunt of their shouts, but never took the slightest hint of damage. It was truly a sight to behold, and even the eyes of Hermaeus Mora himself had scarcely seen events that were of a comparable magnitude or excitement.
Despite their brave, valiant efforts, the two warriors were of no match for the avatar. The battle ended in his favor, but not after some considerable time of defense put up by his opponents. The dragon's life was ended when the avatar had launched his Ebony Blade at them, lodging it in the dragon's skull.
This act did bring forth a rage unlike any Skyrim had seen, or has seen since, from the dragon's mortal companion. For just a few minutes, the tide of battle turned, the rage of that fair skinned Nord driving her to destroy her adversary, and she nearly succeeded. However, at one point, she removed the sword from her master's body, and bared it against the avatar. She had scarcely put it within a foot of his person when the sword froze in her hands. The blade being of Mephala's affinity, it was under control of her avatar, and he found that his opponent was completely motionless whilst wielding it. So he took that opportunity and sent forth unto her body a web of crystal needles to impale her flesh.
And that was the end of the battle. The Khajiit had completed the first part of his assignment, and went on to take over the Imperial City as well.
But he had no such luck fighting the Dragonborn, for she was much more powerful than any other. She possessed more power than he could extinguish with any efficiency. But he would not need to worry about that foe as, across Tamriel, in Black Marsh, at that very moment, a Shadowscale Argonian was born.
