The sky was dark, bloody and imposing; carrion birds pinwheeled through its murky depths, only breaking the surface to feed, whetting their ravenous appetites. Corpses lined the once-glorious streets, the cobblestones now a mottled crimson. Among the macabre scene, creatures could be seen clinging to the remnants of their half-lives, struggling to honor the call of their god. Such a sweet call it was- yes, so saccharine- that none with wits to spare broke the silence with death rattles. The song's dulcet, tainted notes sang out in triumph, lamenting the large creature's wounds and crowing a noise of superiority over the afore-mentioned corpses.
The impure call continued, urging its subjects to rise, rise so that their numbers stood as a roiling mass of dark, fetid brutes. Up they rose, paying no heed to wounds in their haste to obey their master, their god, their Archdemon. As one they charged, decimating the already listing forces of their enemy. Taint fell upon the humans, elves, dwarves- no distinction was made when it came to this hellish slaughter. They devoured, but did not take, for this battle was only for victory, not reproduction.
In their horde, they stood as a front against good- as much a reflection of the opposite side as could be.
The Archdemon roared, its reverberating cry deafening the measly Underlings that dared attack it. A swipe of its tail, a snatch of its taloned paws, and Death was summoned once again. The battle proceeded as such until, as expected, the Archdemon grew tired of the ceaseless swatting, choosing to go on the offensive. As mages rained fire down upon it, the tainted god took flight to expel its wrath onto those it believed deserving.
Driven by wild rage, it immediately sought out those whom its taint had claimed. They, instead of obeying, had the gall to resist its beautiful call! Spewing hellish fire, it quickly incinerated all on its path to the Taint-Betrayer. Slicing through the sallow air, all the while keeping its mightily threatening attacks, it parted the clouds, snapping up the birds and making even the stones quake in fear.
Now the demon was so close that the cloying scent of the Taint-Betrayer overwhelmed its senses. Enraged, the Archdemon created a whirlwind in its desperation to reach the Betrayer. It called the Vanguard, knowing even with its base senses that this Betrayer was not to be trifled with.
Primordial shouts of ire rang out in the decimated fort. The 'Spawn charged the sole Betrayer, biting and clawing at places where swords and bows could not touch. The assault continued, occasionally being renewed when their kin was cut down. In less than a candle-mark, the Betrayer had fallen, keeled over in a pool of Darkspawn blood. With a message that defied the scholars' beliefs of Archdemonic intelligence (This one is mine!), the once pure Old God snapped up the Taint-Betrayer, silverite armor dissolving easily as he was ingested.
With a triumphant call, a shake of the head, and a gigantically powerful leap, the Archdemon soared into the sky. It bellowed, the stone fort collapsing under the sole survivors.
The sky on all shores of Ferelden was painted amaranthine that day.
