Seekers of Slaanesh

They are the Riders of Slaanesh, Disciples of Decadence, Darkling Delighters. The Seekers of Slaanesh are the Prince of Chaos’ outriders, darkling Daemonettes mounted on swift daemonic Steeds. Malign of intent and with the predatory swiftness of a striking cobra, Seekers dart across the endless battlefields of the Realm of Chaos, springing ambushes on vulnerable prey.

These daemonic huntresses are swift beyond belief. Some legends say that the Seekers can charm time itself and so travel between the seconds. Other tales claim that the Seekers’ steeds are formed from the guilty desires of all living creatures and so can never be outrun, for who can flee beyond the reach of his yearnings? Wherever the truth lies, to become the quarry of the Seekers of Slaanesh is to doom oneself to an inevitable, torment-filled death.

The Steeds of Slaanesh can taste the Winds of Magic and seek out the spirits of mortals just as a natural creature senses odours on a drifting breeze. Each soul has a unique flavour and, after but a single taste, the Steed can follow that one specific being throughout eternity if it wishes. Their riders find this most useful for, like all Daemonettes, the Seekers are playfully cruel. They delight in running a luckless mortal ragged, pursuing him across leagues and leagues of rugged and broken countryside. Then, when all seems lost, the Seekers break off their pursuit, allowing the prey to regather his failing strength and rekindle a waning hope of escape.

Such hunts can continue for months or even years, with the Seekers goading the mortal to the very edge of mental and physical endurance. Only when the quarry’s mind collapses and he willingly succumbs to their embrace do the Seekers end the hunt and drag his soul back to the Realm of Chaos. With his surrender, the mortal robs the Seekers of their entertainment, but damns himself to an eternity of exquisite torment in the Palace of Pleasure’s loathsome chambers.
