Read the dark eldar page, timeline section. it says that a half eldar slave called vect vowed to take over the dark eldar or something along those lines.

Here it is Halfborn genrally means deformed or stuff like that and if he was half eldar that makes sense.
 * A Legacy Begins (c.M32) - A halfborn Eldar slave -- known only as Vect -- vows that he shall rule the Dark City, even if it takes an eternity to do so. Vect founds the Cult of the Black Heart, the first organisation to openly refer to themselves as Eladrith Ynneas or "Dark Eldar." The Thirteen Foundations of Vengeance are laid down at this time, an intricate code of dishonour destined to spread through the society of the Dark City in the centuries to come. The impact of Vect's rise to power will resonate through Commorragh's history for millennia to come.
