Dain is a former knight captain of the royal guard, the final ruling family of the nation Khaenri'ah. Under Dainsleif's watch, the Gods of Teyvat descended upon Khaenri'ah and utterly decimated the nation. Dainsleif is a tall man, with light blonde hair and blue eyes. He was cursed with immortality but he didn't seem fazed by it, infact he's calm and stoic but never seems happy also. Dainsleif or Dain for short, also known as the Bough Keeper and the Twilight Sword, he is very strong and all.
