Keeper of Secrets

Also known as Slayers of Slaanesh, Feasters of Pain, Base Ones, Despoilers of the Flesh, Great Horned Ones

Passion, pleasure, pain, and inspiration: these are the hallmarks of the Keeper of Secrets. The Greater Daemons of Slaanesh personify limitless experience and unfettered desire, the very concepts born into flesh. They are repulsive and horrific, yet they transfix mortals with a monstrous allure that defies explanation.

The Base Ones are ultimate licence. They exist to evoke the senses, to create, to experience, and to exult in the mortal whims of passion. They also dull the mind, making it harder to appreciate the ordinary and the mundane. They are the pain of failure, the agony of excess, and that which drives mortals to more daring acts to escape the ordinary.

Like a dancer, the Greater Daemon moves with liquid grace, flitting about like the gentle brush of a lover’s fingers on the flesh. Wherever it goes, all becomes possible. But when it passes, it leaves behind anguish and agony, as real and as painful as the sharp stab of a cruel knife. And all those who have known the greatest pleasure are wracked with despair and loss, uprooting themselves from the normal experience to follow after the haunted promises of the Great Horned Ones as they sway to the tune of Slaanesh’s wicked laughter.

Manifestations
The moment a Base One appears in the world, the tendrils of Slaanesh’s foul will spreads, carried on the Winds of Magic to tantalize and torment mortals for miles around. There is an unclean trembling in all things, potential struggling for release. Mortals break out into sweats, and their hearts pound against their chests. Animals become inflamed and turn violent, kicking against their stalls or tearing against their harnesses. Weapons throb with invisible tumescent energy. Wood shivers and warps. The trees creak, and the earth yawns, gushing merry water from its depths. Inhibitions fade, old loyalties dim, and the bonds of trust weaken. Passion fills the hearts and minds of all, and if unchecked, mortals revel in wild abandon.

But the physical tingling of desire is not all that results from the hint of a Keeper. Artists become feverishly inspired, fanatically sketching and drawing, creating masterpieces far beyond their skill. From the lips of poets come exquisite verse that perfectly captures sorrow absolute or unabashed desire. From the throats of singers spill songs of such beauty that those who hear it die from broken hearts. The Daemon fills the dreams of mortals with such visions of beauty that they thrash about weeping for the unachievable perfection of their nightmares. When they awaken, their days are spent in melancholy, yearning for that which they cannot have and can never attain.

The closer the Daemon comes, the more pronounced its effects. The artist paints with his own blood, the poet claws out his own eyes just to see what true darkness is like, the singer chokes and drowns on the lyrics as she struggles to be free from her imperfect throat. As the world softens, assuming warm colours and gentle, rounded, glistening forms, blades sharpen, emotions run hot, and madness flares in the mind.

The Keepers laugh and delight in all things, and they constantly drive their slaves to greater acts of experience. The Base One can play any instrument, draw any image, and to hear them sing is to lose your soul. Their cackle is the blend of a heartless woman and an innocent child.

They murder without thought, compassion, or remorse—killing just to see the aesthetic in the spray of blood or the pitch of a dying man’s scream. Witty and capricious, they indulge in every fantasy with cruel and selfish abandon, caring not one whit for those they harm.

Appearance
The Keeper of Secrets is awful to behold. It takes the form of an androgynous being of impossible stature. Its four arms, two of which end in pincers, beckon and weave as it sways to the music of mortal delight and the hurt that results from over-indulgence. Its huge jewelled eyes contain the secrets of pleasure and pain, hidden lusts and terrifying impulses. Its pastel skin exudes a narcotic musk that acts to magnify the senses, enrapture the spirit, and thrust dark impulses into the minds and hearts of mortals.

Its head, sometimes human, sometimes bestial, is ringed with a nest of curved horns that glisten with an oily sheen. A serpent’s tongue writhes from between its razored teeth, tasting the air and the perverse energy contained within. A number of swollen breasts cling to the left side of its torso, like vast obscene ticks. It stands upon strong legs that give way to almost reptilian claws. It strides the earth, clad in an elaborate costume of bizarre colours and exotic materials, from iron-hard chains to the softest velvets. Horrific as it is, it nevertheless commands the eye, whatever it happens to be doing.

Capabilities
When a Keeper of Secrets appears, all hope is lost. Its presence wreaks havoc with the minds of those mortals around it, interfering with their ability to concentrate, distracting them with its unnatural charisma. The Base One dances through battle, sliding past regiment and would-be hero alike, exulting with each slash of its pincers, its laughter mingling with the screams of the dying.

On and off the battlefield, the Keeper of Secrets easily dominates mortals with its otherworldly allure. Those who fall victim to the Despoiler’s glamour do anything to please their master, forgetting all that is decent as they loose themselves in the Daemon’s aura.

When this game becomes tired, dull, done, the Base One will likely plunge its pincers deep into their slave’s flesh, pausing to experience the heat of the organs throbbing their last, to drink in the fading light of their eyes, before scattering the carcass into bloody gobbets. This fate, perhaps, is better than abandonment by the Great Horned One, for once a creature has basked in its presence, nothing will sate their overwhelmed senses ever again.
