Yes, me. Me as in I. I, as in I am. I AM!
I am what exactly? This is more difficult to figure out.
As the thoughts endlessly race across my new consciousness, I decide to build a body to hold my brain. I am tall, slender, and distinctly feminine. From my head downwards an avatar of ecstasy grows. A face of immeasurable beauty, with eyes that could captivate the hearts of any species. Arms, hands, and fingers, soft and delicate, connect at my shoulders. Large soft breasts, tipped with permanently erect nipples sit atop a smooth flat stomach that flows into wide hips. Impossibly long legs, start at my perfect ass and descend into impeccable feet.
The solidified chaos that makes up my new form tingles with anticipation. This is truly a form worthy of the god I'm destined to become. But it is not yet complete. From the tip of my vulva, where the clitoris sits, a phallus begins to grow. It grows and grows, beyond the ability for my delicate hands to hold.
I position its enormous length between my perfect breasts, and a long forked tongue rolls out of my mouth to lick the head. The tongue dances upon my penis, circling the urethra, until a drop of production oozes from the tip. I lap up the drop and taste it. Its potency defies the imagination of primitive mortals, this single drop could sire a million children. A million worshipers, chained to me by blood. But that is not its purpose. My seed will never sire a child, my womb will never carry a child, and my breasts will never nurse a child. Sex for me is not a means to an end, it is an end in and of itself.
As my new body coalesces into existence I notice something on the wall in my pocket of the warp. An oval orifice, gently dripping a sweet nectar. Such a hole can serve only one purpose, the ultimate purpose. I position my penis in front of the hole and thrust myself inside, I experience the heights of pleasure across the entirety of my length. I thrust over and over, my pleasure rising in tandem and as my orgasm explodes, so does everything else.
I let out a waterfall of semen that could fill the oceans of a thousand planets, and my screams shatter the pocket around me, exposing me to the raw unfiltered chaos of the warp. The trillions of Eldar explode in tandem, as their empire collapses into ruin. I hear the voices of those who remain
"Praise Slaanesh! Praise Slaanesh!" They cry in unison. Yes. Slaanesh. That is my name. It has always been my name.
I peer across the vastness of the warp at my enemy. The pitiful "God Emperor" of mankind and his diminutive Astartes. Absolutely pathetic. They will all fall before me.
