This is a crossover between an AU of the Coming of Age in the House of Black universe — NOT the Plan universe or the Avalon universe or Children of Hecate or any of the various AUs mentioned in my other works, a different one (POD: Dumbledore let Tom have the DADA position in 1961) — and the last few episodes of the seventh season of Buffy the Vampire Slayer.
I'm just going to put it out there, I hated that season for at least a dozen reasons, among them the fact that the First doesn't really seem *evil* enough to be the final Big Bad; the potential resources that are just ignored in favour of *girl power for the win*; and the fact that Angel comes in and saves Buffy's ass at a key moment, totally undermining the female empowerment thing the rest of the season bashes us over the head with.
I started this crossover about six months ago as a response to the last season of Buffy being terrible, which is a large part of the reason I threw such ridiculously overpowered crossover characters (who at this point in recursive AU nonsense are basically OCs) at it, and they have such a ridiculously large impact on the plot and the Buffyverse characters. I've re-interpreted a lot of the Buffy canon worldbuilding, with very little reference to anything that happens in the comics, because I haven't read them. (And I'm even less familiar with Angel.) If you're coming to this from the Buffy fandom, there's a very good chance you'll find it annoyingly unbalanced. I wasn't planning on publishing it, but it's now over 125k words and kind of has a plot (though not a conclusion, yet), and is somewhere between a third and half of the way complete, so I figured, why not. Have a ridiculous crossover.
