Drazhar
Drazhar, also known as Master of Blades and Living Sword (that's what "Drazhar" means) was first encountered at the gates of the Great Shrine of the Incubi in Commorragh. He walked straight into the shrine, cutting his way through any guards who tried to stop him. When he reached the inner sanctum, Drazhar challenged the enthroned Hierarch of the Shrine. The Hierarch stepped down from his throne into the duelling circle with Drazhar and took up a battle stance. The Hierarch's self-assured superiority soon evaporated when his challenger blurred into action. The duel took only a couple of minutes until it ended with Drazhar stepping over the Hierarch's dead body before making a small bow.
No one knows Drazhar's true identity. There are no records of him in any Incubus shrines and no one had heard of him before he walked in to the Great Shrine. Even the name Drazhar is ceremonial, meaning Living Sword. Even though he killed the Hierarch, and has since killed everyone bold enough to challenge him, he hasn't taken up any leadership post, not even becoming a lowly Klaivex. He could become Hierarch by right of conquest, or hold any position he wanted due to his skill, but he seems to totally lack ambition and exist only to kill. This frustrates the other shrine lords immensely, because they have no way of dealing with such a creature.
After Drazhar had invaded the Great Shrine and killed its Hierarch, gossip and rumors started to spread. Some say Drazhar is the Fallen Phoenix Lord, Ahrha, and that Drazhar's armour is filled with nothing but bone-dust. We can't say for sure about the armor, since he's never once taken it off (not even to eat or sleep), but he certainly does have the same stat-line as the other Phoenix Lords, and the Incubi are in many ways a dark reflection of the Eldar Aspect Warriors.
Taller and more lithe than other Incubi, Drazhar is fast as lightning. Dark Eldar warriors move at a blur when viewed by humans. Incubi strike even faster. Drazhar moves so quickly that it leaves other incubi wondering what the hell just happened. He wears an ancient Incubus Warsuit, perhaps even the original Warsuit, which is significantly tougher than those worn by others of the sect. Drazhar uses demiklaives, formerly known as disemboweller blades, which can also be used by deadly Klaivex Incubi leaders.
Gameplay-wise, he's murder on legs, and even has a cute little special ability that lets him teleport around like a daggome DBZ character. However, he's an expensive straight beatstick, without any real tricks to him or skills that buff up your army when you take him. He's good, but you'll have to really throw him in there to get your points' worth out of him.
