Twilight Kin

The background is maintained here.

Twilight Kin are Elves for the most part; depraved, tainted souls that kill for pleasure. Mixing their Elven brethren's battle prowess with a viciousness that is only rivalled by the hatred of the Abyssal beings the Twilight Kin ally with on the battlefield, these dark Elves employ the use of stealth, speed and an unhealthy use of poison when they march to war.

Of these dark-hearted Elves, the other Kindreds will not speak to outsiders, but that they remain a part of wider Elven society is without doubt, for ambassadors of their kind are often found in Ileuthar. The Twilight Kindred are cruel and unforgiving, their hearts tainted by their proximity to the birth of the Wicked Ones during the Sundering. It is said that they believe themselves touched by the fallen gods, and thus fated to one day rule all of Elvenkind as masters.

History
Elves are as capable of evil as they of good, and although most choose a life of goodness, there are those to whom wickedness is irresistible. For long ages the Twilight Kin were a network of secret cabals within respectable Elven society whose membership was made up of the jaded and perverse. They would meet under dark skies to celebrate the shadowy sides of the Celestians, for the ancient deities of Mantica encompassed good and ill within one form.

It was only with the shattering of Fenulian’s mirror that the Twilight Kin gained real influence. As the world fell from perfect balance into violence, certain magically gifted members of these cults sought out the attentions of the Wicked Ones. Flattered by the worship of the most ancient of races, the Wicked Ones provided the mages of the Twilight Kin what they desired – quick and easy roads to power.

With their new-found might, these mage-lords corrupted their kin, appealing to the arrogance of the Elves. They were the first people, they said, they were the true masters of the earth. Too long had they bowed their knees to the Celestians and given too much to the lesser creatures of the world. At such a time, when the world was in uproar, their words found a ready audience. And such Elves who could not be turned by their reason were twisted by magic. The Eastern and Southern Kindreds in particular lost many of their brothers and sisters to the darkness, a secret that is never acknowledged today.
