End of the Cycle reference?

[SirAlexius]

Is the End of the Cycle referencing something specific?

I finally just finished Legacy of the Void and it made me think that the ending is a little bit similar to this quest chain? Did anyone else pick up on this?

Its a reference to Warhammer 40K, the birth of Slaanesh through the hedonism of the Aeldari race specifically.
