Lumine was fighting the harbringers.

Lumine, Xiao, Venti, Zhongli and the adepti along with her. You, an adeptus there too. Your all facing off against the fatui, plus Signora, Childe and Scaramouche.

Until while your defeating another mage, Signora appears behind you driving her sword through your chest, dropping you to your knees infront of her. Its as if time stopped.

Everyone stopped fighting. You. The adepti with the most power and closest to the archons, on your knees, blood drooling from your mouth and wound. Everyone is watching frozen, Signora a smirk upon her face

“No-“ Xiao yells kicking away the abyss mage he was fighting

Scaramouche and Childe themselves are shocked and horrified watching.
