The twin-soul-riven "Traveler" awakens in Teyvat, with hazy prophecies of the plot in his left hand and the bone-eroding echoes of Khaenri'ah in his right.
Paimon is his only anchor of salvation, but the Abyss sneers at him in the mirror: "You stole his life."
To survive, he steps into Mondstadt. A butterfly's wings unleash waves of apocalyptic destruction: Inazuma's bloody tide rose early because of me, Sumeru's scholars hunt commoners, and the Tsaritsa's throne delivers an ultimatum: "A soul from another world is the original sin!"
Now both the mortal world and the Abyss are prisons. The traveler, carrying a lie, will eventually understand:
He is both the blade that pierces the veil of fate,
and the world's most vulnerable weak point.
