Long ago, when Chaos was first unleashed upon the world, the Elven champion Aenarion drew the dread Sword of Khaine from its altar and used its terrible power to save his people from annihilation. When Aenarion died, his son Malekith was deemed unsuitable for the throne. Although he was a mighty warrior, a great sorcerer , a brilliant general and the rightful heir, many Elves opposed his coronation. They feared he was too focused on war, and potentially a de-stabilizing influence on the High Elf race. In retaliation, over many years Malekith engineered a terrible civil war that divided the race of Elves into two factions.

It was the High Elves who emerged victorious and drove the evil Dark Elves out from the ancestral home of their race. Under the leadership of Malekith the Witch King and his Sorceress mother Morathi, the Dark Elves sailed across the Great Western Ocean and founded for themselves a new kingdom in the northern reaches of the New World. This land they called Naggaroth, meaning 'land of chill'.

Unlike the High Elves, who continually seek to suppress their passions lest they be overcome by them, the Dark Elves willingly embrace their hedonistic nature. Dark Elf society emphasizes individualism, selfishness, and pride. They have little regard for one another and even less for the other races of the world, whom they see as potential slaves and subjects.

In battle, the ruthless warriors of Naggaorth blend Elven discipline with savagery and ferocity, for the patron deity of the Dark Elves is Kaela Mensha Khaine, the bloody-handed God and the Lord of Murder. Nowhere is this more evident than in the beautiful and deadly Witch Elves, who serve in the Temples of Khaine and revel in violence and bloodshed.

Since their expulsion from Ulthuan, the Dark Elves have desired nothing more than to return to Ulthuan and avenge their defeat, reclaiming the land they believe to be theirs by right. In the Age of Reckoning, Malekith learns of an impending Chaos invasion of the Empire and uses this knowledge to set in motion a chain of events that will leave the island home of the Elves defenseless against an invasion. At the Witch King's command, a great fleet of Black Arks – great floating islands laden with soldiers, monsters, and engines of war – sets sail across the sea to conquer the island kingdom of Ulthuan and fulfill the destiny denied the Druchii so long ago.

The Black Guard : The “Tank”
'The Black Guard of Naggarond are the favored warriors of the Witch King Malekith, and are given the sacred task of not only serving as his personal bodyguard, but as his heartless enforcers on the field of battle. Those who would become the Black Guard are taken from birth from their mothers. A Black Guard has no family ties to distract them, they are children of hatred and war and are raised from infancy steeped in battle and blood. Each Black Guard has personally sworn an oath of undying devotion at the feet of the Witch King, it is this oath that lights the fires of hatred and scorn deep in their hearts, for no warrior can be greater then the one chosen by Malekith himself.'
