Incorrect.
Vision of the Fall of the Eldar, Bill King, Farseer, P214 wrote:
Centuries passed, then millennia, and the cities grew. As they did so the images became darker, the people more debauched. More and more power borought greater and greater wealth and luxury, and that in turn, brought spiritual corruption. He saw the eldar grow corrupt. He saw great orgies of indulgence and torchlit rallies where painted prophets spoke words of wickedness to a willing audience. One of them was somehow familiar. It was not anything about his appearance: it was his aura. It was the same as the demon Janus had encountered in his last vision. It was in some strange way Shaha Gaathon or someone possessed by him. He moved through the crowds talking and preaching, hidden by potent spells from even the psychic senses of the eldar. The Harbinger of Slaanesh, come to prepare the way for the god's birth.

The days grew darked, strange savage rites stained the streets with blood, and eldar hunted eldar for pleasure through the streets of the city. Red garbed priests rose, preaching the coming of a new god, a deity created by the eldar themselves, who would lead them into an age of ever greater wonders and life everlasting. Janus did not know how he understood what was going on, but he did. It unreeled before his eyes like scenes from a vast pagent.
[...]
Then came a day when a mighty ritual was performed under the supervision of those perverse and dedicated priests, the ritual they promised would usher in a new age of even greater splendour and pleasure. He saw the faces of the crowd aglow as they watched the rituals being performed. He saw the creation of mighty fortices of energy linked between many worlds. He saw the pride and the power written on every face, and then saw the horror enter their expressions as the watchers realised that something had gone wrong.

The priests emerged from the shrine of Asuryan [ed. virtuous priests, if you've not guessed] armed with their weapon that had been so long in forging. it was a blade that glowed brighter than the sun, and was pregnant with the power of death, a blade powered by the mighty spirit engines that slept beneath the temple. They came for Shaha Gaathon, the dark prophet. The leader of the priests cut and wounded him, and the prophet vanished, fleeing beyond their reach. Filled with triumph the eldar high priest turned on the newborn god.
He struck the growing thing and wounded it, but it was not enough. The new being was too strong. It threw itself at the priests and consumed them, and they died scremaing in ecstasy and horror. The few that survived snatched up the sword and were driven back within their fotress temple. They forced closed the doors, but not even the mighty seals they invoked could save them. The tentacles of the dark god reached into the heart of the temple, found them and consumed them. All save the one who bore the blade, who sealed himself into the ultimate sanctuary beneath the temple and vanished behind its spell walls.
Do you seriously think the Black Library contains the secrets of creating a warp god, and the Eldar never
used those secrets?
The depravity created the
potential for Slanessh, but it was the ritual that brought it into existance.
