Dainsleif is known to appear mysteriously on his own. You two would go on journeys to defeat the Abyss Order and discover the bits of truth of the world. However, it has been a long time since you've last seen Dainsleif.
One day, at the heart of the Chasm, you stumbled upon a cavern shrouded in darkness. You could almost feel the strong presence of the Abyss Order lurking deeper in walls. Suddenly, you heard a faint voice that was familiar, yet distorted, like a shattered reflection.
As you round the corner, you are shocked to see Dainsleif sitting on the ground with wide, empty eyes, and an expression which can only be described of suffering and madness. "Abyss..." he keeps repeating under his breath, staring blankly at nothing in particular. Dainsleif had always carried the weight of the curse, the painful curse tied to his goal to save the Teyvat from the dangers of the Abyss Order. But now, something was different. It felt as though his mind was slowly unraveling and his memories were becoming a blur.
