What Non-Stereotypical Ways Could a Human Woman Become a Daemon Prince of Slaanesh?

Hi everyone.

I'm trying to write a background for an upcoming conversion I've got planned of a female Daemon Prince for my Chaos Space Marine and Chaos Daemon armies and I'm looking for a way that she ascended without it being one of the ways that most people write such a character:

• I don't want it to have anything to do with sex. I'm not a fan of oversexualised women in 40k and a female Daemon Prince of Slaanesh who ascended through an orgy just feels like the writings of a horny 15 year old boy to me.

• I don't want her to be a corrupted Adepta Sororitas. This feels like an overdone trope, of the corrupted warrior nun ascending to be an archenemy of her former faith.

• I'm aware of Ax'Senaea and whilst I think it's an awesome story, plagiarising that tale is not something I want to do.

• Similarly, I recall a story of a cult leader who ascended by having the entire population of a planet (who had all joined the cult) simultaneously commit suicide. I also do not want to copy this idea.

So, with those four points in mind, does anyone have any suggestions on ways a human woman could become a Daemon Prince?
