...assuming that one particular Pseudo-Servant is 'ahead in the queue', so to speak*, a dark-haired tsundere Useless Goddess will have first crack at the (currently-'on-loan-to-yet-one-more-Chaldea') Counter-Guardian.
* - Re: that James D. Fawkes even plans on featuring her at some point, under the assumption that this story makes it all the way to Singularity #7.
Some big gut punches are planned for the American Singularity, and then some mysteries will be slightly cleared up in Babylonia. But... They're both going to be absolutely huge, probably the biggest story sections in the whole thing, and Camelot's probably gonna be pretty big, too. Counting upcoming chapters, we're already past 700k, and I won't be entirely surprised if this story winds up double that by the time it's done. Just on a conservative estimate, that's another year and a half or more to get to the end.
Do you see why I'm leery about doing CITL? I don't want to spend 10 years writing the same story, guys. It's too much.
Having said that, let's be clear. I have no reason to drop this story. It's popular, it's doing well, it gets good feedback and people like it a lot. As much as some part of me would dearly love to move on from fanfiction in general and write more original stuff — looking at you,
Under the Moonlight — I'm not shooting the golden goose, here, to stretch the metaphor a little too far. By every metric (or near enough), this is the most well-received story I've yet written, which means I'd be an idiot to just toss it aside on a whim.
Although maybe, for the health of the story, I should take more frequent breaks. Just...whew. I think I've said it before, but aside from a few holidays here and there? I haven't taken a vacation from writing
Hereafter in two years. Not sure how I've managed to avoid burning out on it like that, but I think the quality has been fairly consistent throughout.
