Keepers of Secrets are the most powerful and brutal of Slaanesh's Daemons. They take sadistic pleasure in murder and torture so are ideal for leading the forces of the Lord of Pleasure to war. Each Keeper has a deep and abiding understanding of the ebb and flow of the warp, and takes particular pleasure in summoning and banishing Lesser Daemons, revelling in its position of power over others.
The Keeper of Secrets combines sensuous pleasure with raw power and brute force. Its bull's head and powerfully muscled body are decked with gorgeous jewels and delicate silks, and its razor sharp claws are decorated with brightly coloured lacquers. Keepers of Secrets are highly intelligent creatures, whose silvered words and lanquid gestures belay their true power. It is claimed that they are the most entrancing of all immortals. As a mortal gazes in awe at the uncanny beauty and mesmerising gaze of the Keeper of Secrets the daemon's mighty claws sweep down and rend its unresisting victim apart.
The Keeper of Secrets' most dangerous power is the ability to overwhelm its enemies with a wave of utter pleasure. The unadulterated sensory overload is too much for any mortal to bear, and the victim's body explodes. The startling effect is called the Aura of Slaanesh. Taken from Renegades
