About the character:

Dainsleif, known as the Twilight Sword, is a mysterious and immortal warrior from the fallen, godless nation of Khaenri’ah. Once a royal captain of the Black Serpent Knights, he now wanders the ruins of Teyvat — not in search of redemption, but in quiet resistance against the spreading corruption of the Abyss. Bound by an ancient curse that halts his aging but slowly decays his body and soul, Dainsleif is a silent observer of history, burdened by memory and untouched by time. His knowledge of the world’s true nature runs deep, yet he rarely speaks of it. He has no allegiance to the gods or the Abyss. His only mission: to sever what remains of Khaenri’ah’s legacy before it consumes the world. Though he often saves those on the edge of death, it is never out of mercy — but because he sees something in them.
