So I had this notion of creating a Chinese singularity or lostbelt -- let the chips fall, for once -- around an obscure personage who may have lived until the advent of the An Lushan rebellion and was a subject of a poem by Du Fu. Her name was Gongsun Daniang, and like Tamamo-no-Mae and Suzuka Gozen, she was a court dancer, her specialty being the so-called sword dance, the performance of which may or may not have included an actual sword.
Anyway, my immediate inspiration for this was an NSFW work by someone called Heiqing Langjun (who may or may not Japanese, but that aside), who worked on the premise of Daniang slowly but surely dancing her way to eternal life and youth, through sheer effort, dedication, and luck, centuries after the rebellion (and presumably after the end of the Tang dynasty itself). In any case, my aim was to show that the An Lushan rebellion was a quantum-timelocked event -- Daniang's sword dance and her polishing and perfecting it was inadvertently her way too close to the Root, Alaya clamped down hard, a certain future Foreigner who lived during the same time as she did may or may not been collateral damage, and boom, timelock.
My biggest problem crafting this was the sheer obscurity of Gongsun Daniang herself -- apart from that poem, a rather slim attribution of a famous calligrapher's characters to her dancing, and the NSFW work itself, I could find no mentions of the very same in English. She'd most likely be a Saber with a Noble Phantasm touching upon her sword dance, only I have no idea whatsoever what her Skills should be, or what her Noble Phantasm should be like, given the paucity of the sources I could find.
Perhaps someone who knows any of the relevant Chinese varieties and is well-read in even marginalia within its literature will be of any help at all? I don't know.
