It's an older one, but I don't remember how old, or a title or author or anything helpful like that. It involved Xander fixing up a house and living there with Spike. Spike playing Master of the Hellmouth, hosting a gathering of other vampires with Buffy and the rest of the girls helping out (I think Dawn was in there?). Might've been more than one story, possibly a series? I d know it's definitely not Ladycat's "A Place Called Home". I thought it was but that seems to only be a one parter without most of the things I'm remembering.
So. Any ideas? TIA.
Found! "The Resoloute Urgency of Now" by Emelye over on Spanderfiles. Link's in the comments. Thanks for the help!
