Coming in version 3.6 of Honkai: Star Rail is Evernight (Grumpy), a darkened version of March 7th. Revealed as a Memory / Ice character, Evernight is expected to be part of Castorice.
Evernight Ascension Materials
A realm of memories cut off from the world, where the candlelight shines on the past and quietly fades into the mist.
From the shadows comes the child of Memory, Evernight, heir to the golden flames of "Time." Stirring the waves of "Oblivion", she guards the wishes of the mirrored self.
——“Don’t worry. I’ll protect the path of ‘Trailblazing’... no matter the cost♭.”
