About 12 years ago (yes, that long) I read a oneshot that was based on the line "You and your museum of lovers" from the No Doubt song "Bathwater". It featured a statuary garden of all of the women who had beaten the Labyrinth and Jareth was being a jerk like, "You didn't seriously think you were special, did you?" and I'm pretty sure he turned Sarah into a statue as well. Possibly smutty, as I mostly read smut or Dark!Jareth. It was most certainly a short oneshot.
If no one knows what I'm talking about I won't be shocked; it's an old story, Google was no help, and Marysia has vanished- something I still lament.
Any help is appreciated.
