Swim the warm waters of sins of the flesh - erotic nightmares beyond any measure, and sensual daydreams to treasure forever. Can't you just see it? Don't dream it, be it. To love, the doors of hysteria, fantasy, and madness may be flung open.
And more than the sight of it, I love the taste of it. The taste of hot, freshly killed blood Condone first degree murder! Filth are my politics! Filth is my life! Take whatever you like. Slaanesh is the Chaos God of perversion, Hentai , shamelessness , excess , the most disgusting Pop Music in the history of ever. Slaanesh was 'born' read: Thus, the final chaos god is known as the one that was literally murderfucked into existence. As a result, Slaanesh owns almost every last Eldar soul in the entire galaxy.
In the event of an Eldar dying without a spirit stone, she becomes Slaanesh's sex toy for all of eternity day and night forever and ever excluding Exodites, whose soul will automatically go to their planet's world spirit and Harlequins, who are scooped up by the great clown himself, and the faithful of Ynnead.
That is why Eldar are willing to manipulate entire worlds into exterminating each other just to save one of their own. The Dark Eldar takes this up to eleven by sacrificing other souls to Slaanesh so that they don't get eaten.
Khorne hates Slaanesh because their a prissy little shit, but Slaanesh doesn't care about Khorne, or any of the other Chaos Gods, until their done playing with themself, which is about 1 nanosecond every millennium, so about 13 nanoseconds total so far. Rumors that their relationship is beyond hate and occasional angry sex are just that; Khorne is not telling though Mork and Gork are alluding to some exceedingly voracious tales. Of course, that paragraph is Slaanesh's WH40K history.
