Spike rules over hell on earth

It's been a long time since I read this and can't remember where. Spike makes a deal with a god/goddess (I think starts with L...Lily, Lillian, not sure) and Buffy wasn't able to stop it. The world turns to hell and Buffy tries to stake Spike but he just rematerializes after dusting. She's like the only human left except for some other people who are used for food. I think Willow and Xander were turned into vampires. Does this ring a bell to anyone? I remember much smuttiness between Spike and Buffy, but not much else from the story. Lol!

Moments in Time by Laure Alexander is a spuffy fic series that is a sequel to Lily. It's one of my favorite series. Drusilla rules over hell on earth with everyone else her helpless captives, whether forced to rule by her side (Angel) or serve in her 'court' (Spike) or forcibly turned (Xander and Willow).... It's not for the fainthearted but it is a world I cringed at and loved to visit. Laure's site is Moon Madness and all of the series are located there.

i know this one!! yay it was margot's fanfiction im pretty sure. it is primarily spuffy but bangel at the beginning and end. All too Human is the one im thinking just google margots femfic sorry i couldnt post the link hope that is what you are looking for! i loved that story even if the ending wasnt spuffy

about the last post it was Lilith, Mother of Demons in the story. the summary for that one isnt too descriptive so i recommend opening the story and reading a bit to be sure.
