Hahahah, that's the story of my fannish life, in a lot of ways. I'm not sure what my overall word count is, for any one rare fandom or rarepair, but as just one example I've got a Vayne/Penelo fic (Final Fantasy XII) that's a WIP at 125k words and counting. And my Eiko/Kuja (Final Fantasy IX and one of the few things I've ever actually finished and even posted at my journal, go me!) clocks in at 75k. (If Tifa/Sephiroth from Final Fantasy VII counts as a rarepair, I've got those too!) (And, oh, don't get me started on my crossovers or rather fusions--- MCU/Downton Abbey, Downton Abbey/Star Wars sequel trilogy, Last Duel/Kushiel-verse....) Anyway, yeah, self-propelled fannishness and ficwriting is, as I say, the story of my life.
