I'm trying to remember a time travel story. I forget exactly how it happens but Buffy and Spike are thrown back in time and get stuck. The PTB send Doyle back to play emissary. Spike eventually claims Buffy as his mate. They spend something like 25 years back in time forming a coalition of vampires before they eventually start a new bloodline with Spike as the sire. It's all part of a PTB plot to build a group of warriors.
Eventually, after being gone something like 75 years, the Scobbies pull Buffy forward to the present. And spike was waiting decades to reconnect with her.
And there are several other stories in a semi-series
Arg! I wanted to download the story but can't remember the author or her website. I think it's one of the "spike's" like spikesdeb, spike_spetslayer or something. Any help on the author or website would be great! |
