Since the beginning of the Xianzhou Luofu arc in Honkai: Star Rail, many fans had become invested in the lore of the High Cloud Quintet. This influential group composed of Jing Yuan, Yingxing (now known as Blade), Imbibitor Lunae (also known as Dan Feng/Dan Heng), Jingliu, and the late Baiheng. The attention was mostly centered on Blade's apparent hatred of Dan Heng, and the past they shared before they were banished from the Xianzhou.
