Dainsleif is an upcoming playable character in Genshin Impact. He was announced in the stream celebrating the release of Genshin Impact.
The confluence between the past and future.
The original calamity had been overturned, yet the island in the sky set the earth to burn. Chalk pursues gold, in this time inopportune, the eclipse is swallowed by the crimson moon. The future must atone for bygone mistakes, as the bond familiar falters and breaks— of the same blood, elders and the youth... Such is the cycle of the world, in truth. Dain, what is that strand of blonde hair to you? Someone you must kill? Or the object of your penitence?
—A self-proclaimed prophet
